About this tool
See how a color looks to people with common types of color blindness, using known transform matrices applied in linear light, all in your browser.
Frequently asked questions
What types are simulated?
Protanopia (red-blind), deuteranopia (green-blind) and tritanopia (blue-blind), alongside the unchanged normal view.
Is the simulation exact?
It is an approximation using standard transform matrices; real perception varies between individuals.
