See through different eyes
👁️ Color Blindness Simulator
Drop in a UI screenshot or any photo and see it the way ~8% of men see it — protanopia, deuteranopia, tritanopia or full monochromacy, side by side with the original.
Check a single color
Simulation uses the standard Brettel/Viénot dichromacy matrices (a close approximation). Prevalence: deuteranomaly+deuteranopia ≈ 6% of men, protan ≈ 2%, tritan ≈ 0.01%, full monochromacy ≈ 0.003%. Design tip: never encode meaning by red/green hue alone — add icons, labels or brightness contrast.
