When looking up how many colors the average human eye can see answers vary between 1 and 10 million colors. So why are computers and TVs bothering with 256 million to 281 trillion colors? I get that it may help with digital enhancement but what good are those enhancements really if we cannot naturally see them?
Normally there are about 16 million colors visible on a screen. This number comes from the multiplication of a pixel's subpixels. There are 3 subpixels in each pixel; one for red, green and blue each. Each subpixel has a value that ranges from 0 to 255; so 256 units. 256 * 256 * 256 gives you 1,703,936 million colors. While all of these colors are technically different, if you compare similar colors like R255/G255/B0 and R255/G254/B0, they'll look practically identical. The differences in 1 to 10 million colors comes from which initial numbers you're using. On screens it's (almost) always 1,703,936 million colors. Even if the screens colors are better, the images are still using the same subpixel units in the digital color encoding. In real life there are more or rather stronger colors, because digital colors are still limited compared to e.g. sunlight. The 280 trillion hexachromatic colors and hues that come from the impossible binocular combination of normal trichromatic colors (the concept is called chromatic rivalry resp. impossible color combination) are a completely different dimension compared to the normal trichromatic colors. And I mean that literally and metephorically. There are about 8 million times more unique color experiences possible with impossible color combinations. That's a number you cannot even compare to the measly amount of trichromatic colors. And the hexachromatic color space is 6-dimensional instead of 3-dimensional. These impossible color experiences are only really possible in VR, because it uses 2 screens. With each new color you can give an image with more color information. While the maximum with normal trichromatic colors is about 1,7 million visually distinguishable details on a screen, with impossible colors you can make the image about 8 million times as detailed. Imagine any normal image that you like, and give it 8 million times more visual details and the result is exceptional. Because we can digitally really only work with RGB images and data, these 280 trillion impossible colors can be used to make the colors in the trichromatic color space much more distinguishable. So, to build on the earlier example, you can make R255/G255/B0 and R255/G254/B0 as different as black and white by the implementation of new impossible and unique colors. It doesn't matter whether we can "naturally" see them or not. What matters is whether we can use them to enhance color vision and color discriminability, as well as to encode images with more visual details. The same thing goes for dichromats (in this exemplary case deuteranopes) which see the same spectral range as trichromats, but can resolve less colors within it due to a missing cone type. Trichromats, although they can see the same spectral range, have a huge advantage because they can distinguish more colors within this range.
@@ooqui Thank you for such an in depth explanation.
My optometrist gave the test tetrachromacy and I passed, odd for males. After the tests I did feel kinda special as I see the world differently than most!
idk how you dont have even 1000 subs yet but i hope you blow up soon
Color vision, although almost everyone is in some way interested in it, is still a niche topic. More sensational and "normal" content is what the people are drawn to. After 11 years of KZread experience I know that being successful on YT comes down to luck (i.e. the algorithm needs to like you), taking opportunities at the right moments, having big KZreadrs as your 'friends', and naturally also your skills as a video maker and entertainer. Give it some time and I'll eventually have 1000 subs and more.
@@ooqui fr. I think you deserve a lot of attention because all of your videos seem to have a lot of effort. I was watching and assumed you had a lot of subs. The way you present information is clean and concise and it’s all interesting. Don’t give up bro.
Fascinating. I subscribed and hope you'll return the favor. Thanks.
Hey, I am doing a project for school and would like to know what the name of the glasses you bought are, hopefully I can find them on Amazon. If you have a link that would be awesoeme. Thank You so much :)
It depends on what effect you're looking for. For red monochromacy you need glasses with lenses that have a strong (and pure) red tint. The same goes for green and blue. For dichromacies color mixtures of these 3 colors. To simulate protanopia (red blindness) you need strong cyan tinted glasses and for tritanopia (blue blindness strong yellow tinted glasses. However, you cannot accurately simulate deuteranopia (green blindness) with merely tinted lenses, due to how human color vision works. In general, the better the color quality of the lenses, the better they simulate a reduced color vision. For starters I recommend Anaglyph 3D-glasses due to their relatively low price. They always come in a pair of two complementary lens colors, so you'll have a different color effect in each. But you can just close one eye. The cyan of the red/cyan Anaglyph 3D-glasses is almost always perfect for simulating protanopia. Yellow tinted lenses are quite rare for 3D-glasses. But there are magenta/green 3D-glasses. Google for "Rainbow Synmphony" and you'll find a website with a lot of such special effects glasses. The quality is quite okay for their price, but buy at your own discretion.
this is so helpful thank you! I have been doing research on it for a project and some of the tests you showed really helped with that!
its just... green.
You need a VR headset for these impossible colors to work correctly. And you need to watch the video on the KZread app inside of your VR headset, so that YT recognizes this video as a VR video.
KGLW Brought me here
I had to google "KGLW". And it's funny that that song brought you here.
I don't understand if tetrachromacy allows us to see more colors or not. Trichromats and tetrachromats have the same range of wavelength but tetrachromats can see difference between colors, hues and shades better. Does colorblind people have the same wavelength range though?
Yes, tetrachromacy allows you to see more colors. However, if the 4th cone type is positioned somewhere in between the other 3 cone types, you'll "just" be able to resolve the normally visible part of the electromagnetic spectrum better. This basically means no UV or Infrared vision, but A LOT more colors and therefore also color details in the "visible" part of the spectrum. As for color vision deficient (CVD) people, only people with deuteranomaly/-opia have a "normal" cone wavelength range. People with protanomaly-/opia see less reds, and people with tritanomaly/-opia see less blues.
I'm a tatrachromat, but as I look through my eyes since I was born I can hardly imagine how a trichromat sees the world. I mean, since I know it I can now explain, why e. g. I can so easily find grey fossiles in grey stone or green in green colored tiny orchids while hiking but I never thought that there's such a big difference to other people.
It's the same for the comparison between dichromacy and trichromacy. One more functional cone type is just that incredible.
Hmmm. When I compare paintings of dichromats (as the ones of my grandfather) with reality the colours are completely wrong - green leaves are blue, the yellow seems too green. But when I see paintings of trichromats the colours are generally ok. I think, we tetrachromats only see more colour hues - with the effect that the world looks much more detailed. I mean, dichromats can see yellow/orange too. But I've a good example what I mean. Some time ago I took a foto of the crestent moon at the sky shortly after sunset. I was absolutely impressend of the delicate colour gardient of the sky. Nobody else was impressed, they said - yes crescent moon... Nice... - I never thought that they simply can't see it.
As a person who can already see the extra yellow, this is incredibly interesting.

It might lag in 4k, but a 4k resolution is preferable. The video will still run and somewhat work in 1440p, but everything will look more blurry then. This is due to how VR videos work and are constructed. This is (sadly) the maximum resolution currently possible. The more you learn about impossible colors, and the more you study and get used to them, the better you'll be able to identify and perceive them as unique colors. Give your eyes and brain some time to adjust to these new colors and this new kind of color vision. With this said, have fun with this video!
Thank you for researching impossible colors... I always thought our color palette was very limited, not just because of our RGB cones (Some have Y too), but because all of our current clothing, paint, dyes etc are created with these limitations in mind... I'm glad you're pushing the boundaries of color vision... I'm hoping to purchase a VR headset in the future, but I will share your video with a friend of mine who has a VR headset...😻
@@baddkatt9504 Thank you! I can recommend buying a VR headset, because it allows you to have very unique experiences in many ways. (Btw., I love how there are two similar cat model videos on your channel but 10 years apart.)
Hello@@ooqui, Thank you for your reply... I will definitely buy a VR Headset in the near future... I hope someday ZBrush creates a way to incorporate their 3D sculpting program into a VR experience... Haha, thx for checking out my ZBrush Videos. They are both of the same cat model. The red clay one is a muscle detailed anatomy model. I smoothed out that model and painted cream & brown directly onto the Siamese Cat version... The videos are 10yrs apart because I gave up on my dream of 3D sculpting at one point, but now I have renewed passion to begin again 😻👍
I’M YOUR 500TH SUB
This is one of the most fascinating subjects to me. I want to be able to see and perceive all the colors that Ive never seen before.
oh hell yeah we gettin shrimp colors with this one
Not with this video's setup. But with the app that I'm currently developing, named "Color in Color", you can see 280 trillion colors (approx. hexachromacy). That's 8 million times more colors than a normal trichromat can see. "Color in Color" is more comparable to an idealized mantis shrimp vision.
@@ooqui yeah, I haven't really watched the video yet. I wanted to leave a comment so I could find it and I left this bc I thought it would be gunny
AKA being high and eating shrooms
Man I’d love to have a pair of these glasses myself. And I’m exceedingly curious to see how you’ll accomplish equivalents of pentachromacy and especially hexachromacy. I assume you’ll make use of an artificial cyan cone for pentachromacy somehow, but how or if it could be done together with the glasses with the yellow lens in this video I can’t wait to find out. I’ve been deeply into in the science and philology of how the brains of tetrachromats might truly create new colors in their extra color dimension and what they may look like, in similarity to the new colors trichromats’ brains have compared to dichromats. I’ve been creating new computer models of color space and also applying impossible colors to the new dimension in an effort to approximate what tetrachromatic colors might theoretically feel like. And currently I’ve started trying to map out the four dimensional color space of pentachromacy (with very limited comprehension and success😂) I hope to compile it all into one or more videos in my channel in the future. In a similar vein of topic as your videos here but with a slightly different flavor. I’d love to do a collaboration with your channel at some point if you’d be interested.

I think it's unlikely that the world is any more beautiful with more colors. You don't like a sunset because it has a lot of colors, you like a sunset because it's a *sunset,* and you grew up watching them. Most colorblind people don't even notice anything is different until they're tested. It's not any more drab or dull for them because it's what they grew up to see as beautiful. I think anyone's actual reaction to suddently having tetrachromacy would be to freak out rather than appreciate the beauty.
From what I've personally experienced, and I've seen MANY new colors of the past 3 years, colors tend to make everything look more beautiful; especially new colors. Of course, if the inherent shape of something isn't beautiful itself, then a nice color might not make it much prettier. And a sunset, as you said, is still a sunset even with dichromacy. But colors let you see details of things you couldn't see without them, allowing you to literally see more of the world. I've simulated dichromatic vision (protanopia & tritanopia) and although colors were heavily reduced (e.g. basically only yellow, white, blue & black) the objects themselves didn't change much in shape; only in color. Sunsets only become "less beautiful" in my opinion if you have monochromacy or achromatopsia. Totally being unable to see color makes it impossible for you to notice that there's even a sunset. You could just see that it's getting darker. So 'some' color is definitely helpful for perceiving beauty. Increasing one's dimensionality of color vision when going from trichromacy to tetrachromacy yields an exponential amount of new colors. I get that you might think that people would "freak out", but in actuality I believe that these new tetrachromatic colors - although a lot at first - will 'quickly' make sense to them, as they're created orderly, resp. non-chaotically. The sunsets I've seen with my app "Color in Color" and some of my special glasses were indeed more beautiful than normal, in the sense that I could perceive more of what I liked.
I color-grapheme synesthete, although I’m just an associater and not a perceiver (letters and single digit numbers (plus days of the week as well as the months to a lesser degree) have colors in my head but I don’t “see” them that way in reality) so this is really interesting since I’m also fascinated with color perception itself, especially the idea of true tetrachromacy. Too bad my VR headset is not working right now, I can only watch this on my phone right now.😆 Keep up the awesome videos! The world needs more awareness of the science and possibilities of color perception!
I wonder if there's any actually product like this (that automatically converts "normal" colors. Also, I wonder if something like quantum dots - used in TV screens (that take in certain wavelengths and remit the same brightness of light but in other wavelengths), could essentially be used inside a pair of glasses that create this "impossible" colors
Well, my appliaction "Color in Color" (in combination with VR) can already automatically convert the millions of normal colors to any other normal color, however so for only digital due to the nature of the technology. I'm in the process of designing special analogue filter glasses that try to achieve similar effects, also working with impossible colors. The quantum dots sound very interesting and I'll read into that topic, thank you. :)
this may be the most interesting youtube video i've ever seen. to think that white is a hue to them is just... insane
It goes even further than just white being a hue to them. In trichromacy you can only have cone combination like this: R, G, B, RG, RB, GB, RGB; and of course everything in between. But in, for example, type yellow tetrachromacy you can have a lot more unique cone combinations: R, Y, G, B, RY, RG, RB, YG, YB, GB, RYG, RYB, RGB, YGB, RYGB. The new tetrachromatic colors RYG, RYB, YGB (and also RGB) are color categories a normal trichromat couldn't even imagine, i.e. truly unique tertiary colors. They're closer to the tetrachromatic white RYGB, but still unique colors. Just like cyan, yellow and magenta are generally more luminous to us because they're colors you get from combining the luminosity captured by two cones, but are still distinct colors. The tetrachromatic white will be perceptually very bright to a tetrachromat. RGB "white" doesn't just become a hue, it splits up into many different distinct whites. If you like this video, I'm sure you'll like my other videos, too. I've made videos about: how to correct color blindness; how to see octarine, the color of magic; how to see polarized light dichromatically; how simulate grapheme-color synesthesia, and that *with* impossible colors; how to access the human potential for hexachromacy and effectively simulate about 280 trillion more colors; and so on. I'm currently even working on glasses technologies that induces a type yellow tetrachromacy, which'll be my next video. I've made and still plan to do a lot of very exciting projects. :)
@@ooqui damn i keep trying to understand, but it's something my brain literally can't comprehend. makes me wonder if it would be possible to transplant a 4th yellow cone into a trichromat...

Your videos have a High quality but unique style and are also very informative. I have learned alot about colors and the way they work from you. You truly are a hidden gem.

i dont have vr. ... how do i select the cross eye version? when i click on "3d" in the video the only selectable option is "2d" ...
@@thekito4623 You need a VR headset for the effect to work. Alternatively you can watch the video with a cardboard VR headset (or by crossing your eyes) on your mobile phone on the mobile KZread app (with the cardboard VR mode enabled). Otherwise you'll unfortunately not be able to see Octarine and the other impossible color combinations. The 2D/Anaglyph video settings don't apply to this video. If you have other questions I'm happy to answer them.
While I AM NOT goint to make any mockery here, I do think that you should provide human-made CC for your videos. I'm not native English speaker either, but this rtaher thick German (?) accent isn't very conductive to understanding your narrative. Again, I'm not making fun here, and neither I'm mocking you, consider my comment just as a feedback (which it is). Cheers.
I'm someone who loves to get (preferably constructive) criticism, so you don't have to be so defensive when writing such a well-meant but usually not too easy to convey comment in the future. I'm working on my accent, but this is probably a life-long project that becomes better over time and with each video. Thank you for your feedback! :D I may retroactively add closed captions in the future, when I find the time to do so.
@@ooqui Nice to hear from you, I was tad "defensive" as my experience points to people more often being kinda. erm... "unwelcoming" to any remarks that touch on them personally, AND then I didn't know you, so to be on a safe side... And to stress the crux of my message too. Yeah, getting one's accent right is not easy thing to do, and I wish you success in this "struggle". Cheers!
great video! this has way to little views for its quality
holy shit i cant believe you made the music as well
@@timthecringe Almost all of the videos and its contents are done by me. This is a lot of work of course, but you also have more creative freedom that way.
I'm already working on another video (and article on my website) on tetrachromacy, which goes *much* more in-depth into the topic. I've learned and discovered *a lot* in the year since I've uploaded this video.
What a fascinating idea. Do you plan to offer these glasses for sale at some point? If you decide to represent tetrachromacy in different color ranges, would love to see your results.
I wish I could offer these glasses commercially. But I currently don't have the financial means to effectively produces them. This might change if my PC/VR application "Color in Color", that I'm currently developing, sells well. This means that I'm working on making these (and other) special glasses available to everyone, but it'll unfortunately still take more time and effort to achieve this goal.
By the way, I watch HermitCraft religiously, I love Mumbo and Grian's videos. I think the earlier seasons were way better though.
Hey Ooqui! This is Drake! The reason I havent been active is because I have been grounded for the past week or so. I am ungrounded on the 14th or 15th. Sorry for the inactivity, I am commenting on a school computer.
The way I have to construct my VR videos for KZread specifically and due to KZread's compression my VR videos have a 'relatively' low resoltion. Impossible colors work better the better the resolution is, but this video's resolution is good enough. In my app "Color in Color", with which I made the color enhancements you can see in this video, the resolution, bit rate and frame rate is naturally MUCH better. Read the video description for more info, and the video's warning/info at the beginning, in order to understand how to watch this video, how this video was made, and more info on Hermitcraft. (more info will be added in the future) Have fun watching this video! :D
2 x chromosomes are needed to get this trait, you have to be a woman or a transexual man to be tetrachromat.
Yes, that's generally correct.
What I'd really be interested in is if the vr app would apply the filters while in other games! I'd be curious to see to see what some places, like worlds in vrchat for example, look like with impossible colors.
I haven't actually watched these videos in vr yet, so I'm still missing out on the experience as of now. But I like the information I'm hearing. Will edit upon rewatch
My application "Color in Color" applies the filters to what's visible on the desktop. As the desktop is always 2D, everything you look at will also be 2D. So you can play games like Minecraft or watch KZread videos normally, with all the selected impossible colors. For "Color in Color" to work in 3D with VR games, however, I would need to be able to access information from those games which aren't (easily) available to me. Most VR games aren't designed for others to be able to access the VR camera data. Most are not even setup in a way where there are two distinct cameras which send different signals to the two eyes (at least in the way I need it for my app). A VR game would likely have to be changed and its cameras' data made available so that "Color in Color" could work in 3D. So, it's not impossible, but currently VR games aren't built to easily allow for the creation of impossible colors. However, If this somehow becomes possible in the future I'll 100% integrate a VR game functionality! :D
@@ooqui I believe it may be possible with steam vr overlay addons, since ovr toolkit can adjust screen brightness and colors. Though I don't know that those settings can apply to the left or right display only
Finally watched the video in vr (not many options to watch on index so I had to use a quest) It was both more and less jarring than I assumed. I went from not being able to differentiate color, to swapping between the two, to only seeing out of one eye, to seeing a lot of blue. Then finally, I started seeing yellowish, orangish, and pinkish blue
@@TheCreationKing Initially, impossible color vision is something alien to your brain. Your brain can see impossible colors due to binocular redundancy, but it has to learn how to see them properly. Because your brain likes to have both eyes' colors the same, because it's used to that, it tries to somehow "correct" or "neglect" impossible colors, by e.g. shifting the focus to only one of your eyes, or creating visual artifacts like colored spots instead of a uniform impossible color experience. Impossible color vision is an investment. The more you look at impossible colors, the more your brain will learn to understand them; especially in the right context. You can't and shouldn't expect to magically see and understand impossible colors on your first try, as they're something new to your brain. If you'd magically become a tetrachromat for a day you wouldn't really be able to tell colors apart correclty in that short amount of time also. Let time and neuroplasticity work for you. It takes time and practice to learn, understand, recognize and correctly identify all these impossible colors. And because there are literally 140+ trillion impossible colors − about 8 million times more colors than you can normally distinguish − this is a task even I, the one who's very likely seen the greatest amount of impossible colors in all of humanity, struggle to fully keep up with. I've looked at billions of impossible colors in numerous contexts and each day I'm seeing a new color in a new context I've never seen before. The impossible colors shown in this video are only a tiny − and I mean a really tiny − fraction of all the possible impossible colors, in an even tinier color and situational context. This video shows maybe 0.00001% of all the possible impossible color combinations, at most. For example, it doesn't show impossible color combinations of differing saturation and luminance levels, which add two whole new dimensions of impossible color combinations and crazy new impossible colors. (I'll show those in another video in the future.) Just treat impossible color vision like any other skill. The more you do it, naturally, the better you'll become at it. Immerse yourself in impossible colors, learn their names, learn how they're constructed and perceived by your eyes and brain, how they influence you, and how they alter your understanding of the visual world, etc. The more you do that the more you'll understand the true potential of human (impossible) color vision.
i crossed my eyes to do the simulation .... i must say im really really not impressed ... ive had much more improved vision in other ways before ... this was kinda weak ngl ... sry :S
If you think that 140+ trillion new impossible colors are not enough then you're greatly underestimating that number. This video showed maybe just 0.001% to 0.01% of all the possible impossible color combinations at most. There are much stronger and more vivid color combinations possible, and much more vivid custom color spectra and spaces. Color vision, even though genetically somewhat standardized, is very subjective. It depends on the type of screen you're using, on the color quality of that screen and the resolution of the image, how good and near the 'standard' your own color vision is, how long you've been looking at impossible colors, how well you know the colors' names, how many impossible colors you've already seen before, how your eyes focus when crossing your eyes, whether you have a more domination eye, etc. To me, this color vision with impossible colors is incredibly beautiful, with colors I couldn't even imagine before, and image/video details that I wouldn't even have recognized with my normal trichromacy − even when I tried to look for them. This impossible color vision is an investment, the more you do it the more your brain will understand it and you'll see and recognize these impossible colors better. Also, this video is already 8 months old. I've further developed my application "Color in Color" since then and I've incorporated a lot more functionalities and impossible color settings.
ive got another way to make the colors more intense and the color perception more nuanced: magic mushrooms (im not joking)
Well, "magic mushrooms" might work, ...but then you're also doing "magic mushrooms", which I don't ever want to do.
This is not fully correct. Colour vision works on opponent processes and not lacking a colour from RGB. The fact that so called red and green cones, actually peaking in yellow and green) are very close together means that protan and deuteranopia will appear very similar as the same opponent process (red-green) is affected and the remainng red or green cones function similarly! Thus deuteranopia (green blindness) will not look like a blue red spectrum and cannot be simulated with magenta glasses as shown in this video
You are correct that you cannot 100% correctly simulate "real" deuteranopia with magenta colored glasses. However, the method shown in this video is the closest normal trichromats can get to a color vision similar to deuteranopia without active technology. This simulated deuteranopia and real deuteranopia are not the same, but spreaking from personal experience I can say that real life colors (like those from trees, flowers, etc.) look very similar to the "real" deuteranopia's colors. Deuteranopia is in fact the only dichromacy you cannot 100% correctly simulate with such passive tinted glasses. On the opponent process between the three cones: In my personal experience I find the opponent process theory not entirely accurate. While protanopia and deuteranopia will look more similar than e.g deuteranopia and tritanopia, if you'd compare both side by side, both protanopia and deuteranopia send different information to the brain. That's why if you had deuteranopia in your left and protanopia in your right eye you would still functionally be a trichromat. Such a color vision would be weird and work with impossible binocular dichromatic color combinations, but it would behaviorly be very similar to normal trichromacy. The L ("red") and M ("green") cone types are indeed relatively close together, but they're distinct enough to send unique information to the brain. From my experience a deuteranope's color vision would look red and blue, with a dichromatic "white" as their midpoint. And protanopia would look green and blue, again with a dichromatic "white" as the two colors' midpoint. It doesn't matter whether the red/green is actually a red, a green, or a yellow for these two color visions, but what matters is that they send different color information to the brain. To a red-green dichromat, whether they're a deutan or protan, the actual color experience of the only two opposing dichromatic colors wouldn't matter because both colors would naturally be complementary.
@@ooqui I still diagree, I think the closest normal trichromats can get to deuteranopia is to have a narrow bandpass at each other their cone peak sensitivities of blue and yelow. Yes the this should make the oranges and greens equally bright and indistinguishable with the drawback of darkening red. Using a magenta lens skews the darkness of the greens a lot and misrepresents the indistinugiability of the oranges and greens
@@maciejzajaczkowski4965 I made the mistake of generalizing without any specification. Of course there are other methods to simulate color vision deficiencies like deuteranopia more accurately. The easiest way to simulate the (probably) most accurate representation of a form of deuteranopia is with digital technology and using color altering algorithms. And you're also right that the magenta glasses do not perfectly simulate deuteranopia/-omaly, but they're closer to this reduced color vision than to typical trichromacy or any other dichromacies.
What website did you use to make and simulate the triaptochromacy?
The visualizations of this "triaptochromacy" you see in this video aren't made with any special website. It's an animation that tries to represent what I see with the special glasses that evoke this kind of enhanced color vision. I animate everything myself using Unity and other little programs. If you meant something different, then please elaborate.
Usually how I explain what i see to others is rhat i see colors in other colors but thats not the only thing it is i jist dont know how else to explain it
But most screens only have red, blue, and green colored pixels, so it would be impossible to tell based of a test on a screen
I don't know which part of the video you're referencing, but you're technically correct: It's basically impossible to display or simulate all of the possible tetrachromatic colors using only trichromatic data. For example, with just RGB data we don't have any information about something being "pure yellow", because to a trichromat yellow is always a red-green mix. A "yellow cone tetrachromat" should easily be able to distinguish a "true yellow" from a seemingly "yellow" red-green mixture. While we cannot display or simulate all of the possible tetrachromatic colors using an RGB screen and RGB data, we can however approximate them. Humans are virtual hexachromats (see this article I wrote for reference: sites.google.com/view/color-in-color/impossible-colors/human-hexachromacy?authuser=0 ). By making use of impossible color combinations, which can be identified and perceived as distinct colors, we have enough unique colors at our disposal to simulate a form of functional tetrachromacy. However, you either have to draw new tetrachromatic images using such a simulated tetrachromatic color space made up of impossible colors, or you can only look at trichromatic images with a small subset of all the tetrachromatic colors simultaneously, if you want to convert RGB into tetrachromatic images. As for the detection of a tetrachromat using a screen or other more scientific tests (which I think is the topic you refer to in your comment): To a real *functional* tetrachromat, which most genetically tested "tetrachromats" probably aren't, a RGB screen would look as dull to them color-wise, as a dichromatic (e.g. deuteranopia) image would look dull to us trichromats. However, even with more scientific tests we can never be sure on the actual qualia of the colors experienced by such a functional tetrachromat. Even if they behaviorly act very similar to how a tetrachromat is expected to behave color-wise, it's still difficult to determine both the functionality of their genetically tested tetrachromacy, and how they actually perceive and experience these colors. It's similar to the same debate about color perception as always: "Is my red your green, and your green my red?", because we still (sadly) cannot look and experience the world through the eyes of another person (yet). I have special glasses (I've already made a few videos about them) which simulate a better color vision. Wearing them and comparing what colors I can see in real-life compared to the same colors taken by my mobile phone it's incomparable. There's just so much color information missing if you compress the entire *visible* light spectrum into RGB data, that the colors are comparably dull. My conjecture is that you can, in fact, test for tetrachromacy on a RGB screen, but not using the currently main-stream and silly tests, which are most often just attention grabbing uninformed articles, but it's not easy to do so. It would basically be a reverse test for tetrachromacy. It wouldn't be: "Can you see more colors on this screen than irl?", but rather: "Can you see *significantly* less colors on this screen than irl?". This conjecture is based on my own technologically enhanced color vision, and still remains to be tested on more individuals. I hope this has helped in your understanding of tetrachromacy.
thanks for the upload! i now discovered a very interesting topic
In the future, I'm going to make a few more videos on tetrachromacy (and how to simulate it). It'll be very interesting because I've learned a lot about this topic since the upload of this video about a year ago. In the meantime, if you want, you can also click on my channel and check out my other videos if you're interested color vision and enhancing it.
Tetrachromats do NOT see more colors than we do! They can just tell the difference between certain shades of color better than trichromats. The fourth cone doesn‘t increase the colors, cause it doesn‘t add anything new to the spectrum. The range of wavelength that they can see isn‘t increased by the fourth cone.
Thank you for your criticism, but you're incorrect. Functional tetrachromats do see more colors and hues. A functional fourth cone type increases the dimensionality of colors you can see by an additional color dimension. This happens regardless of whether the new cone type happens to be between the already existing cone types, as long as it's distinct enough. By your logic, if a deuteranope − someone who can only see red and blue (and no other hues) and with subsequently no green cone type − wouldn't be able to see any new colors and hues if you would bestow the missing green cone type upon them. But not only the opposite is the case, there are even colors created − when going from dichromacy to trichromacy − which cannot exist dichromatically. An example of such a color is magenta; a virtual color your brain makes up if you perceive both red and blue, but no green light; a color which has no associate single wavelength. Single visible wavelengths are (without a human experiencing them) independet of colors, but single visible wavelengths (and any combination thereof) are always interpreted as having a color, like the combinatory color magenta proves. When a deuteranope gets a functional green cone type they'll be able to see colors like a trichromat. They'll have a better color discriminability and a new dimension of color (in this case: green) with which they can compare the colors they could see before to create new color experiences (like purple or cyan). While with deuteranopia only R (for red) and B (for blue) was possible and their dichromatic mix would be experienced as white (RB), with trichromacy you can see R, G (for green), B, RG, RB and GB, and many more unique in-between colors. With the dichromacy 'deuteranopia' everything's either red or blue, no other hue. When we upgrade from trichromacy to a functional form of tetrachromacy, like with an additional "yellow" cone type, our color dimensionality increases again; and exponentially on top of that. In tetrachromacy the following color combinations are possible: R, Y (for "yellow"), G, B, RY, RG, RB, YG, YB, GB, RYG, RYB, RGB, YGB, and "white" (RYGB). That's 15 distinct colors, 8 more than in trichromacy, with even unique tertiary colors (i.e. RYG, RYB, RGB YGB), which are totally new color concepts unimaginable to trichromats. The quality of these new colors and hues might vary based on the functionality and distinctiveness of the new 4th cone type, but a new color dimension is added nonetheless. In this kind of tetrachromacy there are multiple "unreal" colors, like the trichromatic magenta. These are: RG, RB, YB, RYG, RYB, RGB, YGB. There's not just one "unreal" color like the trichromatic magenta anymore, but more. Such colors cannot be displayed by a standard trichromatic representation of colors/hues. While you can, for example, display all the trichromatic hues (not colors, so just the spectral colors) in a hue circle, in tetrachromacy you cannot do that. For tetrachramacy you need an unfolded tetrahedron's sides and edges to display all the possible tetrachromatic hues, and the entire volume of that tetrahedron to display all the possible tetrachromatic colors (saturation only, without luminance variants). New color information doesn't come from the visible light spectrum, but from each additional functional cone type. A tetrachromat, whose new cone type lies within the trichromatic visible light spectrum, doesn't perceive entirely new visual information, but they perceive new color information by being able to perceive a multitude of more colors, which then results in new perceivable visual information on its own. If the new 4th cone type would be most sensitive to UV light, for example, and would thereby lie outside of the trichromatic visible light spectrum, it would only add more visual UV information, but not significantly new color information compared to a RYGB tetrachromat. Tetrachromacy is a very complex topic. It's like comparing the 3rd and the 4th spatial dimension.
You‘re right with dichromacy, but with 3 types of cones you can already see the whole spectrum (that humans are able to see). As I said, the fourth cone doesn‘t add anything new to that, thus they aren‘t seeing more colors. They can tell the difference between shades of colors (especially yellow hues) easier than trichromats. But not whole new colors, as trichromats can already see the whole spectrum. Do you have any sources to back up your statements? Btw, are you German?
@@crazybarley4817 By your answer I appears to me that you didn't understand the point I was making. I was specifically talking about deuteranopia, not just any dichromacy. Normal trichromats are essentially "just" deuteranopes with an additional green cone. Then trying to argue that trichromats don't really see more colors than deuteranopes, and that the third ("green") cone type doesn't increase colors, would clearly be incorrect. Trichromats see many many more colors than deuteranopes do. In fact, trichromats see another whole new dimension of color (i.e. the "green" dimension). Color is not an intrinsic property of light, but a visual property made up by our brain, with our eyes as its tool. The experience of color is created by comparing the excitations of the different kinds of cone types that you possess. One more cone type and there's a whole new dimension of color you can compare all the previously perceiveable colors to; and this includes "white". For why functional tetrachromats do see whole new hues and colors, please reread my previous comment thoroughly. Let's make a thought experiment and say that your theory was correct: How would a tetrachromat be able to tell different shades of yellow hues easier apart compared to a trichromat if a tetrachromat cannot perceive more colors? Just making the original trichromatic colors stronger doesn't work because it would be contradictory to the tetrachromatic cone excitation values. How would a tetrachromat be able to identify one yellow from another if it's not a significantly different color? Again: The visible light spectrum doesn't determine how many colors we can perceive. Our amount of distinct cone types in combination with our brain, which compares their varying excitation values, determines how many colors we can perceive and distinguish. We could see half the visible light spectrum (e.g. only light between the wavelengths associated with "turquoise" to "red"), but if we had the same amount of distinct cone types, just closer together and a bit more narrow, we would see the same amount of colors but within a smaller visible light spectrum. I'm currently writing an article on my website about tetrachromacy and I'll make an updated future video on this topic is as well. Both will go in-depth into how you can understand (and functionally simulate a form of) tetrachromacy, with clear visualizations. You'll find sources and links to interesting related articles and studies there and then. (Yes, I'm German.)
I know that people with deuteranopia, protanopia and tritanopia see „less color“ than people with trichromatic vision do, but I don‘t know about tetrachromacy, as trichromats can already see the whole spectrum. But I kinda understand what you mean. I‘m looking forward to that video, maybe I can understand it better then. Grüße aus BaWü
So we… see more colours. No need to be insecure about it mate
*How to watch this video:* Open the KZread app on your VR headset and play this video in full screen OR watch it with a cardboard VR headset (or by crossing your eyes) on your mobile phone on the mobile KZread app (with the cardboard VR mode enabled). It might lag in 4k, but a 4k resolution is preferable. The video will run smoother in 1440p, but everything will look more blurry then. This is due to how VR videos work and are constructed. This is sadly the maximum resulotion possible currently. Additionally I've also implemented a version of the impossible colors you can see in VR that shows these colors as time-based/temporal colors. So you can watch the video also without VR on the right screen, but of course the experience isn't the same then. The upper small screen is just a screen with the original colors for an immediate comparison. The screen in front of you displays all the impossible colors as binocular combinations. And the screen behind you displays them as temporal alternating colors, which are a preview of the impossible binocular colors for those of you who don't have access to a VR headset yet. The more you learn about impossible colors and the more you study adn get used to them, the more you'll be able to identify and perceive these impossible trichromatic color mixtures as their own unique colors. Give your eyes and brain some time to adjust to these new colors and this new kind of color vision.
*IMPORTANT DISCLAIMER & ADDENDUM:* - 1:45 In this case I specifically mean tetrachromats with a 4th "yellow" cone type most sensitive to approx. "lime" light. If the 4th cone is most sensitive to infrared or UV, then tetrachromats can perceive more of the electromagnetic light spectrum. - 5:15 Fully functional tetrachromacy not just adds a new "rainbow of colors[/hues]", but rather an entirely new dimension of color. Meaning that e.g. an originally trichromatic white (RGB) itself becomes a hue that can mix into a tetrachromatic white (in the video's case: RYGB), when it closes in on the new tetrachromatic color. It would be better to say that tetrachromacy adds an enitrely new dimension of colors to a rainbow, which is experienced as many new hues inside that rainbow, as a rainbow is displaying colors 2-dimensionally in a spectrum format. - The visualizations of tetrachromacy you can see in this video are very simplified. I'll make another video in the future, which goes a lot more into detail on how to functionally visualize and behaviorally simulate a form of tetrachomacy.

At least one of your sources (New York magazine) is incorrect. The notion of seeing 100 million colors as a tetrachromate is an incorrect extrapolation. Aside from the factual stuff the video is beautifully made and it's surprising to see this channel not have the number of subscribers it deserves.
*IMPORTANT DISCLAIMER:* By "yellow tetrachromacy" in this video I mean that you'll mainly see more (impossible) colors in the green to red color range. Thereby, yellowish colors will be enhanced the most. Although this kind of enhanced color vision appoaches a form of tetrachromatic vision, it does so mainly in the green to red color range. This means that this is not a full, but rather a partial form of tetrachromacy; allowing you to see what someone with a color vision close to tetrachromacy might see in the yellow color range.
colors in the brain of a animal or human is not in the chemical form but in electrical signals. its not the pigment that make up color even it play a role in the chemical exhange axon dentries. its frequencies created in the brain of the animal that produce color.
Bro hell nah, these vr videos are too much for me to handle
Impossible colors are something you have to learn to perceive to some extent; or rather you have to learn to understand how to perceive them. This kind of impossible color vision can be unstable in the beginning. But once your brain is used to seeing these impossible colors, it'll be almost as normal as seeing normal colors. If you mean VR videos in general, then I can't help you with that.
@@ooqui ah sorry, I've never really encountered a vr video before and I only saw this while on my phone. on pc its way more tolerable, but I still think for these kinds of educational videos it might be too much information at once that you have to actively try to spot. the colors are still weird, but I think I got the gist of what you were showing.
I don't have a VR headset 😢
There are only three methods of experiencing impossible colors (so far). 1. Crossing your eyes to overlap the two different colors. This method works well, but it strains the eyes. And not all people can cross their eyes. 2. Temporal Colors: Using time as an additional dimension to alternate between two different colors isn't the same experience as seeing impossible colors binocularly. But it's similar enough to at least be comparable. But quickly changing colors can be quite disorienting if you're not used to it. 3. Using a VR headset to do the eye crossing for you. With this method you'll admittedly need a VR headset, but once you have a VR headset, then impossible colors and color visions like the simulated tetrachromacy I've shown in my video, become quite easy to render and experience. So unfortunately, you'll need a VR headset to really experience these impossible colors and this simulated tetrachromacy.
For the colour previews I suggest moving them in/out vertically instead watching cross eyed and having those previews move out horizontally is quite disorienting But very interesting, I’ll def check out the app once I can
i dont have a vr headset so id love to know how how effective people find this. if u could get it working lemme know :D cool vid
I'm very eager to find that out myself. I've already tested it on myself many times, while simulating protanopia, and it worked really well each time. But you never really know until you put it to the test on real color vision deficient individuals.
That's was amazing 😍🤩, can't wait to see what's come next 😊❤❤❤
Thanks! Next up I'll render all the major impossible color combinations in a single video. It'll be at least a 60 minute video, which will show 360.000 distinctly identifyable impossible colors.
