Overview
Coblis is a browser-based simulator that shows how an uploaded image appears under eight types of color vision deficiency, with side-by-side comparison and pan-and-zoom. It runs entirely client-side, so nothing leaves your machine. Designers use it to sanity-check mockups, charts, and color-coded UI against red, green, and blue deficiencies.
Why we like it
- Eight color-blindness simulations
- Runs client-side for privacy
- Pan and zoom on results
