Color Test

A color test is often used to determine whether patients have a deficiency in their color vision, most commonly called color blindness. There are several different types of color blindness. Two kinds of color tests exist. The first type is screening tests, which can determine if there is an issue with an individual's color vision, and more detailed and quantitative tests can be used afterward. If individuals have a color deficiency, these tests help determine the type of deficiency and the severity of color blindness. The test most commonly used for screening is called the Ishihara Color Vision Test, which involves colored dots with numbers in the center. Individuals with color deficiencies won't be able to distinguish the number because all the colors will look the same way. This test can sometimes help determine the type of color blindness an individual has as well.
