What Is Color? | Physics in Motion

The concept of color is explored as we learn about subtractive and additive color mixing. We examine what types of colors form when we mix different wavelengths of light. Properties and uses of pigments and dyes are discussed; the concept of luminance is introduced; and we see what makes an object transparent, transluscent or opaque.

    Seen all videos from top designers and countless "science" youtube channels. Yet a video of a dude in a church calmly explaining what colour is made me understand. Wish this dude was my teacher. Fantastic, outstanding & amazing job.

    light is made out of photons , these photons are realeased when and electron inside and atom change it's state, like when it drops from it's position or the opposite, so if an object absorb light means that these photons get consumed as energy by the electrons of that object, and if the added energy usually gets transformed to some other form of energy like heat to keep the balance

    when i see something like this i always think how similar animals and humans are. Like the eye is such a unique and crazy thing that can do so much. I mean, what must have happened in the evolution do develop something like that. And all the animals have it, such a specific thing, but still the same in humans. Seeing different wavelenghts in different colors could be something aliens couldn't even imagine to be possible

    Is the angle of the waves make up the cross like the heat of hydrogen and sound and carbon or oxygen when 90 ° we get visible light if above 90° is spirit or soul or consciousness moving away and blue it get closer that is why the day more alert while get sleeper at night

    Color is a product of our eyes… and it is subjective to the receiver, so there’s no inherent color to anything. Light is energy, but it isn’t particularly anything until it is received by our eyes. So yes , you are correct that our vision is a simulated interpretation of the input received by our eyes and processed by our brains. But this doesn’t in any way reflect reality. It’s just our version of reality.
