I’m a big fan of Mark Changizi, also from Rensselaer Polytechnic Institute! He has contributed a funny and interesting article on color to Discovery Magazine. Here he argues that our perception of color is anything but arbitrary, I would call him a “color naturalist”.
“Why should it be acceptable to warp colors but not shapes? I’ll suggest here that it’s not acceptable—that once we appreciate the meaning of color it becomes apparent that we shouldn’t arbitrarily engage in color distortion.”
