Ishihara Test

Free online color blindness test with algorithmically generated plates

Webfreeglobal

Ishihara Test is a free, private online color blindness screening tool using algorithmically generated Ishihara-style plates that are never the same set twice, unlike most static online tests, with results and a downloadable PDF in 13 languages. It's aimed at designers, professionals in color-sensitive fields, and anyone curious about their color vision — a screening tool, not a medical diagnosis.
