Color Blindness Simulator
Simulate how any color appears to people with Protanopia, Deuteranopia, Tritanopia, and Achromatopsia.
How to Use Color Blindness Simulator
The Color Blindness Simulator is a free online tool that shows how any color appears to people with different types of color vision deficiency. Select a color using the picker or enter a hex code, and instantly see how it looks to someone with Protanopia (no red cones), Deuteranopia (no green cones), Tritanopia (no blue cones), or Achromatopsia (total color blindness). This is essential for designers and developers building accessible interfaces, ensuring color choices work for all users regardless of color vision. Use it alongside the Color Contrast Checker to create truly inclusive designs. All simulation happens in your browser using color science transformation matrices.
Step-by-Step Instructions
- Select a color using the color picker or enter a hex code
- View how the color appears with normal vision
- Compare simulated colors for each type of color blindness
- Copy all color values for documentation or testing
