Like Spinning_Sandwich, I don't think that color is qualitatively different in its problematic-ness than e.g. pitch of sound, or perception of geometry, or even memory of a smell, or any other aspect of consciousness.

Color just serves as the easiest referrenced example of the mystery because colors feel as largely an irreducible sensation (you can perhaps reduce it to two separate sensations of hue+brightness, or something like that, but not much further, like one might do by trying to reduce geometry to points and numbers)
