• Are you color blind? • Know somebody who is color blind? • Think somebody is color blind? Contrary to the name color blind, most color blind people are not blind to color. A more accurate description is color deficient. We see color. You just don't see it the same as we do. (Perhaps it is really you who are color deficient and we are normal.) About 1 in 20 males are color blind. About 1 in 200 women are color blind. The color blind gene is carried by the daughter to her son. For example, my mothers father was color blind. My daughter's may have a son who is color blind. Not every sibling is color blind as example by none of my brothers are color blind. These series of images in this app are designed to provide a test which gives a quick assessment of color vision deficiency of congenital origin. This is the most common form of color vision disturbances. They are referred to as the Ishihara for Dr. Shinobu Ishihara (http://en.wikipedia.org/wiki/Ishihara_color_test).
