Also choose your retina. ;-) Human retinas have substantial variations in
the cone (color) photoreceptors (RGB). Changes in a single amino acid of
the photoreceptors cause shifts of their absorption curves and thus give
rise to differential hue discrimination. These variations are hereditary
but different from "color vision deficiency". ("Color blindness" is not PC.
;-)) There is no assuming that you and I have the same color vision.
