Preview protanopia, deuteranopia, and tritanopia
Paste a HEX color and choose a color-vision deficiency. The simulated RGB uses a standard matrix approximation for protanopia, deuteranopia, or tritanopia.
This is a planning aid for palettes and charts, not a clinical test. Check contrast as well with the Color Contrast Checker.
Simulation stays in your browser.
