Color Blind Test & Simulator

See the world through colorblind eyes. Simulate protanopia, deuteranopia, tritanopia & more to design inclusive, accessible products.

See exactly how your colors look to someone with protanopia, deuteranopia, tritanopia, or any color vision deficiency — instantly, on your own photos and palettes.

Built for designers, educators, and anyone who wants to check color accessibility fast.

WHAT YOU CAN DO • Pick any hex or on-screen color and instantly compare it across every type of color blindness, side by side. • Re-render your own photos through any deficiency to feel exactly what others miss. • Audit a palette for color pairs that collapse under CVD, scored by contrast and color 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.
