i think butterflies are red-green colourblind, but they are able to distinguish colours in the blue to ultraviolet part of the light spectrum. would you believe that humans are born colourblind? 1 out of 40 000 babies never develops cones, so they never see any other colour but black and white. i think it's sad to see nothing but black and white, and equally sad to be able to see all the colours but not see the truth. but then again, maybe it's just another case of one-or-the-other.
