The Wikipedia article “color vision” gives a description of color vision in various animals.

I don’t know where your cat people are on the evolutionary scale, but I don’t know why they should be limited to the type of vision felines have.  Primates having color vision evolved from animals that did not have it.

I’m working on this with my reptiloid Litorians.  Just what kind of human physical characteristics has evolution given them?

Because of the symbolism of six in the Sefdaanian culture, the Ethrans, having experienced the rainbow and light refracted through a prism, have come up with six basic colors: red, orange, yellow, green, blue, and violet.  Then there are six intermediate colors: reddish-orange, orangish-yellow, etc.  There are two prefixes for lighter shades and two for darker shades.  This results in names for 60 different colors.
The Ethrans themselves are tetrachromats and can see into the ultraviolet range.  The other five Peoples are trichromats.

The Lithans have a tapetum lucidum to help them see in their mines.

Subject: Re: Revising Lindiga color words

Might I ask for a little bit of advice? I am working on a language for a race of cat-people, and I have done some research into how cats see colours, light/shadow etc. I was wondering if you might be able to give me pointers based around that idea? How else might vision impact language? Do you have any more information on feline vision?
