Color Blindness Simulator
Upload an image and see how it appears to people with different types of color vision deficiency.
Understanding Color Blindness and Accessible Design
Approximately 8% of men and 0.5% of women worldwide have some form of color vision deficiency. Our simulator helps designers verify that their images and designs remain understandable for users with different types of color blindness.
Protanopia and Deuteranopia (red-green color blindness) are the most common types. Tritanopia (blue-yellow) is rarer. Achromatopsia (complete color blindness) is the rarest form. Testing your designs against these simulations ensures inclusive, accessible visual communication.
