About this screening
These plates are generated procedurally to illustrate the red–green confusion effect. Color-blind individuals may have difficulty distinguishing certain color pairs because those colors fall closer together along a red–green confusion line. A demonstration plate is shown first so you can confirm the task.
This test is not a substitute for professional color vision testing. Lighting, screen settings, and other factors can influence your results.
