Color Blindness Simulator

What is Color Blindness Simulator?

Color Blindness Simulator shows you how your images and color palettes look through the eyes of people with different types of color vision deficiency. Test for protanopia, deuteranopia, tritanopia, and achromatopsia to ensure your designs are accessible to everyone.

How to use

1. Upload an image or enter colors you want to test for accessibility.
2. Select a color blindness type to see the simulated view side by side with the original.
3. Compare all simulation types at once and download the simulated images for documentation.

Result

A UI designer uploads their app's dashboard screenshot and discovers that their red/green status indicators are indistinguishable under deuteranopia, prompting them to add icon shapes alongside colors.
