CORRECT COLORS
ON EVERY SITE
A browser extension that re-colors any web page in real time so you can tell colors apart — maps, charts, dashboards, red warning text. Pick your type of color blindness once and it follows you across the whole web.
In review on the stores now. Want it today? The camera version runs in your browser with nothing to install, and developers can load the extension unpacked from GitHub.
HOW IT WORKS
Click the toolbar eye and choose a mode. The page's colors are re-mapped so the differences your vision normally compresses become visible again (daltonization, via an in-browser color filter). Your choice is remembered as you browse.
It corrects, it doesn't simulate — the point is to help you see, not to show sighted people what color blindness looks like. It runs on the same published method as the rest of OpticQuiz: Machado (2009) simulation, scored with CIEDE2000.
