If you suspect you might be color blind, there are several ways to determine your color vision status. Color blindness tests, like the Ishihara test, are widely used to diagnose color vision deficiencies. These tests are often available online and can be administered by an eye care professional for a more accurate diagnosis.

What Is Color Blindness?

Color blindness, or color vision deficiency, is a condition where individuals have difficulty distinguishing between certain colors. It is often inherited and more common in males. The most typical forms are red-green color blindness, but there are other types, such as blue-yellow color blindness and complete color blindness, which are less common.
