I, for example, am deuteranomalous. The next level is pentachromacy, which is five-dimensional color vision requiring at least 5 different classes of photoreceptor as well as 5 independent channels of color information through the primary visual system. And theres indeed a good genetic reason why tetrachromats are more likely to be women. Women get two X chromosomes, one from their mother (XX) and one from their father (XY). Do EnChroma Glasses Work for Color Blindness? Red-green and yellow-blue are the so-called forbidden colors.

It started with this photograph, the blue and black (or is it white and gold?) . The normal explanation of tetrachromacy is that the organisms retina contains four types of higher-intensity light receptors (called cone cells in vertebrates as opposed to rod cells, which are lower-intensity light receptors) with different spectral sensitivity.
