Libre Color Blindness Simulator
See how your design looks to people with color vision deficiencies. Simulates protanopia, deuteranopia, tritanopia, achromatopsia, and milder anomalies.

Paano ito Gumagana
Color vision deficiency (CVD) is simulated using Brettel-ViΓ©not color transformation matrices β the standard algorithm used in accessibility tools.
- 1You drop an imageThe image is loaded into a canvas in your browser. Pixels are downsized for performance (max 1200 px on the longest edge).
- 2A 3Γ3 color transform is applied to every pixelEach CVD type has a specific matrix. For deuteranopia (green-blind), red and green channels get mixed in a way that mimics what people with only L+S cones perceive.
- 3The transformed image displays alongside the originalSwitch between CVD types to see how the same image looks for the ~8% of men with some form of color vision deficiency.
Your image stays in your browser. Even the simulation math runs locally on your CPU β no server, no API, no upload.
