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
- Start the test and look at the first color plate carefully
- Enter the number you see in the dot pattern — or select 'I can't see a number'
- 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.
