About Color Blindness

Around one in twelve men and one in two hundred women have some form of color vision deficiency. This simulator shows how an image or palette looks to people with protanopia, deuteranopia or tritanopia, so you can catch charts, status colors and UI states that depend on color alone.

How to use it

  1. Upload an image or enter the colors of your palette.
  2. Switch between protanopia, deuteranopia and tritanopia.
  3. Compare the result with the original and adjust any colors that become hard to tell apart.

Frequently asked questions

Which types of color vision deficiency can I simulate?
Protanopia (reduced red sensitivity), deuteranopia (reduced green sensitivity) and tritanopia (reduced blue sensitivity), applied to images or to color palettes.
Is the simulation a perfect match for real vision?
No. It is a visual approximation that helps you spot problems early. For critical designs, never rely on color alone: add labels, icons or patterns, and test with real users when you can.
