Very interesting, I would never have thought of it this way. I wonder if there are ways of building information visualization tools along these lines too.
Color blindness is usually classed as a disability; however, in select situations color blind people have advantages over people with normal color vision. Color blind hunters are better at picking out prey against a confusing background, and the military have found that color blind soldiers can sometimes see through camouflage that fools everyone else. Monochromats may have a minor advantage in dark vision, but only in the first five minutes of dark adaptation.
The United States Military has found that color blind individuals can be more easily trained as snipers due to the fact that they are more acutely aware of differences in texture and pattern and thereby less likely to be fooled by camouflage patterns.
