Overview
What RGBlind does.
RGBlind is a free toolkit for colour accessibility. It simulates eight types of colour-vision deficiency from an uploaded image or a live camera, checks WCAG contrast, generates accessible palettes, and runs vision tests — all processed locally in the browser for privacy. It helps teams design for the ~300 million people with colour-vision deficiency.
Designed, built, and operated by SaaSatura LLC. We own the product and its roadmap.
