From Wiktionary under the GNU Free Documentation License. Color blindness, or colour blindness, a color vision deficiency, is the inability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or exposure to certain chemicals. The English chemist John Dalton published the first scientific paper on the subject in 1798, "Extraordinary facts relating to the vision of colours", after the realization of his own color blindness. Because of Dalton's work, the condition was often called daltonism, although this term is now used for a type of color blindness called deuteranopia. Color blindness is sometimes classed as a disability, however, in certain situations color blind individuals have an advantage over those with normal color vision. There are some studies which conclude that color blind individuals are better at penetrating certain color camouflages and it has been suggested that this may be the evolutionary explanation for the surprisingly high frequency of congenital red-green colour blindness.

(Color blindness doesn't really work like that, they don't typically see one color as another, they usually don't see it at all when its combined w/other colors. For example, many color blind ppl cant see fuscia which is a combination of red,wh, yellow & blue. they see hot pink (red, wh, blue.) To mistake green for gold is a feat. Green is yellow & blue, so if he were color blind yellow he's see blue, if he were color blind blue he'd see yellow, but gold is a hue formed from the presence of yellow & red. I would imagine if he were being honest he's color blind blue (which is extremely rare) and he'd actually be seeing a… [cont.] Answered by jjohnson94107 - Sat Mar 7 00:39:30 2009 Can men pass the the color blindness trait to their children? Q. My friend and I have an argument on our hands and none of our old college text books.

The man can pass his bad allele on to his girl children. Whether or not the girl actually has the trait depends on mom: If mom is normal, girl will be a carrier. If mom is carrier, girl may be carrier or girl may have trait (50-50). If mom is colorblind, girl will be colorblind. The man cannot pass his bad allele on to his boy children.
