About the Color Blindness Simulator
This simulator shows how a color appears to people with different types of color vision deficiency. Upload an image or enter a hex color to see how it looks to someone with protanopia (no red cones), deuteranopia (no green cones), tritanopia (no blue cones), or achromatopsia (complete color blindness).
Around 8% of men and 0.5% of women have some form of color vision deficiency. Designers use this tool to ensure their UI, charts, maps, and infographics remain legible and meaningful for all users — a key part of accessible design and WCAG compliance.
