Do Men and Women See Colors Differently? The answer is, "Yes," at least for about half of women. Around half of them are tetrachromatic, which means they have 4 types of cone receptors instead of the usual 3 (trichromatic). They can actually see more colors. For example, in a rainbow, trichromatics can see 7 colors: red, orange, yellow, green, blue, indigo and violet. But tetrachromatics can distinguish 10. [2/8/2007]
