How can you determine whether you are color blind or not?

Do the Ishihara test: A person can determine if he is color blind by taking the ishihara test. This test consists of 38 circles of colored dots. Each of the circles of dots contains a hidden number made up of certain colors of dots. Depending on whether or not a person can read the number in the circles, his type of color blindness can be diagnosed. Parts of the ishihara test are posted on websites for people to use.

Testing: You can compare your color perception with someone known to be color normal. An ophthalmologist has available color perception test booklets to determine whether it is present, and what spectrum the deficiency lies within. This is important for certain occupations.
