I was looking online and I found that there are a lot of different bases for color. We talked in lecture about RGB and CMYK, but there are many more! https://en.wikipedia.org/wiki/List_of_color_spaces_and_their_uses
I thought the most interesting was YUV family which was used in old TVs which stored brightness and color.
I learned in my multimedia class that color basis are spilt into two types: nonuniform and uniform. RGB and CMYK are perceptually nonuniform, while CIELab is. I'm not quite sure how "perceptually uniform" is defined, but the graphs for CIELab do look a lot nicer.
It's interesting that perceptually, color "feels" multidimensional. This is probably related to the fact that the cones in our eyes come in 3 flavors that respond most strongly to different wavelengths. In comparison, the pitch of sound "feels" one-dimensional, at least to me.
