Colour vision check

Can you distinguish subtle colour differences? This activity uses original colour samples and does not copy clinical colour plates.

Important: This is not a validated Ishihara or clinical colour-vision test. Do not use it for driving, occupational or medical decisions. If colour vision changed recently or differs between eyes, arrange a professional assessment.

Before you start

  • Use normal display settings and turn off Night Shift/blue-light colour filters.
  • Avoid tinted or coloured lenses during the check.
  • Use a bright, glare-free screen in normal room lighting.
  • Consider repeating one eye at a time if you suspect a difference between eyes.
