How to Use the Color Blindness Simulator

Add your colors (from design systems, brand palettes, or UI components) and instantly see how they appear under six types of color vision deficiency.

Features

  • Six Simulation Types — Protanopia, Deuteranopia, Tritanopia, Achromatopsia, Protanomaly, and Deuteranomaly.
  • Multi-Color Input — Test entire palettes, not just individual colors.
  • Population Stats — Shows what percentage of the population is affected by each type.
  • Click to Copy — Copy any simulated color value for reference.
  • Common Use Cases

  • Accessibility Testing — Ensure your UI is usable by people with color vision deficiency.
  • Design Systems — Validate that color palettes maintain sufficient contrast across all vision types.
  • Data Visualization — Check that chart colors are distinguishable for all users.
  • WCAG Compliance — Support Web Content Accessibility Guidelines requirements.
  • Why Use This Tool

    About 8% of males and 0.5% of females have some form of color vision deficiency. Testing your color choices against different vision types isn't optional — it's essential for inclusive design.
