Disclaimer
Please read this before relying on any result from this site.
Not a medical diagnosis
The tests on this site are screening tools provided for information only. They are not a medical device and do not diagnose colour vision deficiency or any other eye condition. Only an eye care professional can do that.
Your screen and lighting affect the result
Colours look different on every screen. Brightness, night mode, blue-light filters, colour profiles and room lighting can all change a result, so the same person may score differently on two devices.
Not for job, licence or school medicals
A result from this site cannot be used as proof of normal or deficient colour vision for employment, driving, aviation, the military or any other official purpose. Those assessments must be done in person with approved tests.
