About Pharaoh Vision

Pharaoh Vision is a real-time daltonization lens — an established colour-correction technique. It pulls confusable colours apart so red and green (and blue and yellow) stay distinct for colour-blind vision. It supports deutan, protan and tritan types, with adjustable strength.

It was built by a colour-blind developer who needed it, by Pharoah Technology Ltd. It's an assistive aid to help you tell colours apart — not a medical device, treatment or diagnosis.

Free to use — no account, no card. Works on any phone or computer with a camera.
