About this tool
This tool applies a standard simulation matrix to your colour for protanopia, deuteranopia, tritanopia or achromatopsia. The result is an approximation of how that colour may appear, not a medical test or a diagnosis.
Frequently asked questions
Is this a medical test?
No, it is only a visual approximation and cannot diagnose anything.
Why check colour blindness at all?
It helps you avoid relying on red-versus-green alone to carry meaning.
