About This Tool

The Color Blindness Simulator helps designers and developers understand how their designs appear to people with color vision deficiencies. It simulates three types of color blindness: protanopia, deuteranopia, and tritanopia. Used by accessibility-conscious designers, developers, and educators to test color choices.

Enter a color in hex, RGB, or named format. The tool processes it through CVD simulation matrices and displays how it appears under each color blindness type. You'll see side-by-side previews of the original and simulated colors with hex values.

Perfect for checking palette accessibility, testing UI designs, and ensuring no information relies solely on color. Runs entirely in your browser—no data is sent anywhere and no signup required.
