Color perception is based on the relative amounts of light absorbed by red, gren and blue pigments in the cones. Even among people in the "normal color vision range" there will be some disagreements (just dug out my old neuroscience textbook). Genes responsible for red and green pigments are on the X chromosome, so men are more prone to color-blindness, or to being "anomalous trichomats", not color-blind per se, but a seing colors little different than "normal trichomats". Now, could there be differences tied to ethnicity as well?
That's interesting. My mother had brown eyes, while mine are blue. Could that have anything to do with our apparently different perceptions of blue/green, I wonder.
