Color perception arbitrary?

[Rahul]

I've never understood why our brains/eyes translates different wave lengths into the color we see versus translating them as other colors. Was there some evolutionary advantage to seeing the colors we see the way we see them? Why is it better for instance that we look up into the night sky and see the color black? Why not white? Or why is it better that when we look at the sun we see a blinding white rather than a blinding black?

I know this isn't the type of answer you are looking for, but the reason why our ancestors developed color vision is because we needed to be able to visually tell if fruit was ripe.

There used to be a lot of Great Ape species all living at the same time. But then those damn monkeys developed the ability to eat unripe fruit without getting sick and most of the Great Ape species died out.

Little tail having fuckers.

But no, I got no idea.

I can't answer your question, but here's a color gradation test I think is interesting: http://www.xrite.com/online-color-test-challenge

I tried to drag and drop the colors but it wouldn't work for me. So I just hit the score test button.

It said I had perfect color vision. That thing is wonked.
