Color Blind Test & Simulator

See exactly how your colours look to someone with protanopia, deuteranopia, tritanopia, or any colour vision deficiency — instantly, on your own photos and palettes. Built for designers, teachers, and anyone keen to check colour accessibility fast. WHAT YOU CAN DO • Pick any hex or on-screen colour and instantly compare it across every type of colour blindness, side by side. • Re-render your own photos through any deficiency to feel exactly what others miss. • Audit a palette for colour pairs that collapse under CVD, scored by contrast and colour difference. • Learn the science behind dichromacy, anomalous vision, and monochromacy — explained simply. • Export high-resolution results for decks, portfolios, or reports. • 100% on-device — no accounts, no ads, no tracking, ever. HOW IT WORKS 1. Choose a colour, photo, or palette. 2. Pick a colour vision type to simulate. 3. See the result instantly, side by side with the original. Full access — including photo simulation and palette auditing — unlocks with a subscription, available weekly, yearly, or lifetime. Cancel anytime in Settings. See colour the way everyone else does.
