About this tool
Simulate color vision deficiencies on colors and images in your browser. Compare protanopia, deuteranopia, tritanopia, and more. Color Blindness Simulator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- Color Blindness Simulator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
