The Neural
Control of Vision
J. The Processing of Color
Color
blindness among humans is not uncommon. In males 8 our of 100 Caucasians,
5 out of 100 Asians, and 3 out of 100 Africans are color blind. The probability
is 10 times less in females. There are many tests to assess color blindness.
One of the best known is the Ishihara plates, one example of which appears
in Figure 47. People with normal
color vision see an 8 here.
