Hoe dit werk

Color vision deficiency (CVD) is simulated using Brettel-Viénot color transformation matrices — the standard algorithm used in accessibility tools.

1
You drop an image
The image is loaded into a canvas in your browser. Pixels are downsized for performance (max 1200 px on the longest edge).
2
A 3×3 color transform is applied to every pixel
Each 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.
3
The transformed image displays alongside the original
Switch 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 — no server, no API, no upload.
