Colors - Color Blind Simulator

See the world the way a colorblind friend sees it.

Colors is a color blindness simulator. Point the live camera at anything and watch it shift, in real time, into a different kind of colour vision — then show the people around you what it looks like.

THE LIVE CAMERA
Choose protan, deutan, tritan or no colour at all, and dial the strength from mild to complete. Or load a famous example, like John Dalton's. The view updates on every frame, straight from the camera.

Suddenly "that jumper is green, not brown" stops being an argument and becomes something you can just show each other.

SEE THROUGH THEIR EYES
One tap turns whatever you're pointing at into a split-screen image — ordinary vision on top, the simulation underneath — ready to post.

PLACES YOU KNOW
Central Park in autumn, Dutch tulip fields, the Amazon, a fruit market, a San Francisco street and Rembrandt's Night Watch — each shown twice, so the difference reads at a glance. Add a photo of your own too.

HIDDEN IN THE DOTS
You have seen those circles of coloured dots with a number inside. Colors generates them and lets you flip each one between kinds of colour vision, so you can watch the number fade away and understand why they are built the way they are.

ENHANCE MODE
Enhance pushes easily-confused colours further apart so they are easier to tell from each other. It cannot change how anyone's eyes work, but it makes the difference visible.

THE SCIENCE
The simulation uses the physiologically based colour matrices published by Machado, Oliveira and Fernandes (2009), applied to every pixel on the GPU. A short illustrated tour explains cones, confusion lines and why red-green colour blindness is so common.

JUST A SIMULATION
Colors is made for curiosity, education and fun. It does not test, measure or diagnose anyone's eyesight, and it is not a medical device. Screen brightness, ambient light and display calibration all change what you see.

PRIVATE BY DESIGN
Your camera feed never leaves your phone. Nothing is recorded, nothing is stored, nothing is uploaded. No analytics, no ads, no tracking.
