omg language is imprecise sometimes so fucking profound dude.

An average human, utterly unremarkable in every way, can perceive a million different colors. Vermilion, puce, cerulean, periwinkle, chartreuse—we have thousands of words for them, but mere language can never capture our extraordinary range of hues. Our powers of color vision derive from cells in our eyes called cones, three types in all, each triggered by different wavelengths of light. Every moment our eyes are open, those three flavors of cone fire off messages to the brain. The brain then combines the signals to produce the sensation we call color.
Vision is complex, but the calculus of color is strangely simple: Each cone confers the ability to distinguish around a hundred shades, so the total number of combinations is at least 1003, or a million. Take one cone away—go from being what scientists call a trichromat to a dichromat—and the number of possible combinations drops a factor of 100, to 10,000. Almost all other mammals, including dogs and New World monkeys, are dichromats. The richness of the world we see is rivaled only by that of birds and some insects, which also perceive the ultraviolet part of the spectrum.
Researchers suspect, though, that some people see even more. Living among us are people with four cones, who might experience a range of colors invisible to the rest. It’s possible these so-called tetrachromats see a hundred million colors, with each familiar hue fracturing into a hundred more subtle shades for which there are no names, no paint swatches. And because perceiving color is a personal experience, they would have no way of knowing they see far beyond what we consider the limits of human vision.
Over the course of two decades, Newcastle University neuroscientist Gabriele Jordan and her colleagues have been searching for people endowed with this super-vision. Two years ago, Jordan finally found one. A doctor living in northern England, referred to only as cDa29 in the literature, is the first tetrachromat known to science. She is almost surely not the last. -

2019-09-09 at 11:05 AM UTCColours exist objectively for the same reason Minecraft exists objectively. If you crack open a computer running Minecraft, you won't naively find any Minecraft, just integrated circuitry. Because what Minecraft is, is a simulation that gets abstracted so you can understand what is going on. Colours are the same exact way. It's an abstraction made to represent different qualities of life, what they are, are an information structure. And information structures exist objectively, specially non Shannonian information.

Your perception is an objective fact about the world that is in principle reducible to facts about the physical world. -

I understand. If it's just a simulation of our eye comes and rods I guess there is no such thing as REAL color, so the answer to my question would be the ability to see color since it had to have come first or else color wouldn't even exist.The following users say it would be alright if the author of this post didn't die in a fire! -

color is just the name we give to lights's pulsation at different frequencies as perceived by our eyes.
even if we are color blind, different material will still gives off lights that vibrate at different frequencies. -

You're getting closer but still off.
Our ability to see IS colours. How can you see without representing objects extended in space? How can you "visually" represent objects extended in space? Whatever that is, it's colours. The very fact that you are able to differentiate one thing from another visually, is colours.
You don't get the ability to see colours and it doesn't need to be a similar, vision is colours. -

Well when I asked the "if a tree falls in the forest" thing was in my mind. If everyone in the whole world was completely blind, from day 1, THEN would color still exist?
Or like the minecraft example. Did minecraft always exist even before it was ever invented ? The POTENTIAL of it did, so in essence EVERYTHING exists, but it.. ya know.. doesnt exist either until someone can acknowledge it as a thing.
It's fine make fun of me I'm bad at this.The following users say it would be alright if the author of this post didn't die in a fire! -
