What is Color Blindness Test?

The Color Blindness Test uses Ishihara-inspired color plates to help you screen for color vision deficiency. It tests your ability to distinguish numbers embedded in colored dot patterns, covering red-green and blue-yellow deficiencies.

How to use

  1. Start the test and look at the first color plate carefully
  2. Enter the number you see in the dot pattern — or select 'I can't see a number'
  3. Complete all plates and view your results with an explanation of any detected deficiency

Result

If you can read 74 on plate 1 but struggle with plate 5, it may indicate mild red-green color deficiency.
