Advantage of being

people with red-green color blindness can differentiate between many more shades of khaki than unaffected people. This might help in detecting camouflage in a green environment. Color vision deficient people tend to have better night vision and, in some situations, they can perceive variations in luminosity, that color-sighted people could not. Outlines, rather than colors, are responsible for pattern recognition. In the military, colorblind snipers and spotters are highly valued for these reasons. During the Second World War, it was suggested that color-deficient observers could often penetrate camouflage that deceived the normal observer.
