Jinsi Inavyofanya Kazi
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.
