How CBC works

Color Blind Check is based on the scientific knowledge about colors which can be seen and which not by the people who are suffering from the different types of color blindness. To get more precise results, the test is based on four different main colors and as even colorblind people are quite good in spotting brightness differences, Color Blind Check is shifting brightness constantly.

Compared to other well known tests with Color Blind Check it is NOT possible to learn something by heart and get better while retesting.

Warning: This app is not recommended for persons with epilepsy as the screen is constantly changing colors during the test procedure.
