Color Blindness Simulator
Simulate how colors appear with different types of color blindness. Test your color palette for protanopia, deuteranopia, and tritanopia.

How to Use Color Blindness Simulator
- Enter colors or a color palette to test.
- View how each color appears under different types of color blindness.
- Supported types: protanopia (red-blind), deuteranopia (green-blind), tritanopia (blue-blind).
- Compare original and simulated colors side by side.
- Get suggestions for more accessible color alternatives.
Frequently Asked Questions
What types of color blindness are simulated?
Protanopia (red-blind, ~1% of males), deuteranopia (green-blind, ~1% of males), tritanopia (blue-blind, very rare), and achromatopsia (complete color blindness).
Why should I test for color blindness?
About 8% of males and 0.5% of females have some form of color blindness. Testing ensures your designs are accessible to everyone.
How accurate is the simulation?
The simulation uses established color science algorithms to approximate how colors appear to people with different types of color vision deficiency.
