For some unknown reason, some people are unable to distinguish certain colors, such as red, green, or blue. Two percent of all men are said to blind to red, and equal number unable to distinguish green. Such color blindness is very much less frequent in women. Only one women in every 1250 seems to have any problem in distinguish reds and greens. The difference between the sexes arise from the fact that color genes are carried in the “x” chromosomes, the male having only one “X” chromosomes in which all three color genes must then be present, if he is not to be color blind. Women have two “x” chromosomes, and for this reason any from of color blindness is very rare in women.
People who seem to wear outlandish color may do so because of color blindness. They may actually believe that a suit is gray, when in reality it is brown, red, or even green. School boys who are color blind often paint seas and lakes purple, thinking they are using green. Unfortunately, nothing can be done for these people. Most of them have to depend upon there features, such as size, shape, and texture, or the opinions of friend to guide them in their choice.
