There are millions who have no clue. No clue until they take a colorblind test, frequently, the Ishihara test with symbols or numerals in a circle of color dots. There 32 million who have some sort of colorblindness and 8% are men and .5% women. The colorblindness gene is mostly a male issue.

Most colorblind people have a red-green or blue-yellow blindness. What this means is in certain color combinations or shades of those colors adjacent to one another, the color blind person sees the color but may misinterpret it. A colorblind person sees all colors, they do not see in black and white! I have a green-red problem when taking the tests. My daughter has a blue-yellow problem. She had no idea she was colorblind until given the test with numeral 7. Like anything, severity varies from bad or mild. I have a problem with shades of green, red and brown. As a person ages, a blue-yellow colorblindness may develop. Most men will have the red-green problem because it's a recessive gene carried on the X chromosome and passes from grandpa to grandson. The woman who receives a defective X chromosome from a colorblind father and another carrier mother.

Colorblindness usually impacts shades of the impacted colors and not the primary versions of them. But, it is dependent on how they are used. For those on Wall street, where green and red lights on monitors indicate status, the size of the light display and shade plays a role. That is why, there are also + and - symbols.

Many jobs require no color blindness and no matter how qualified you are, if you are colorblind, look for another job. These are: pilots, air traffic controllers, TSA officers at airports, police, railroad engineers, lab technicians and many more.
