Color Blind Test: Can You See the Hidden Numbers?

About this test

A color blind test with 10 plates of colored dots, each hiding a number. The first plate is a check that everyone can read, six plates test red-green color vision and three test blue-yellow. The plates are drawn fresh every time from color pairs calculated to look alike to people with color vision deficiency, and each dot varies slightly in brightness so the number cannot be spotted by brightness alone. Your score shows how well you tell red from green and blue from yellow.
