Last updated 2026-11-09

The tests, simulator and articles on Color Blind Test are provided for general information and screening purposes only. They arenot a medical device, do not provide a medical diagnosis, and are not a substitute for an examination by a qualified eye care professional (optometrist, ophthalmologist or other licensed practitioner).

Results are estimates

Online color vision tests are affected by your screen’s color reproduction and brightness, display settings such as Night Shift, True Tone or blue-light filters, ambient lighting, viewing distance, and how you answer. Your result may be inaccurate. A “normal” result does not guarantee normal color vision, and a result suggesting a deficiency does not confirm one.

When to see a professional

• If your result suggests a color vision deficiency and you want a diagnosis.
• If you need color vision certified for a job, license or school (for example aviation, rail, military, electrical or maritime roles). Only official tests are accepted.
• Promptly if you notice a change in your color vision, color vision that differs between your eyes, or other vision symptoms. Acquired color vision changes can be a sign of eye or general health conditions.

Children

The kids’ test is meant to be used with a parent or guardian. Please confirm any concern with a pediatric eye examination.

Mentions of color-enhancing glasses or other aids are general information, not medical advice or a recommendation for your specific situation. Some links may be affiliate links; this never changes how the test scores your answers.
