Upload an image and instantly see how it appears to people with eight different types of color vision deficiency — an essential accessibility check for designers, developers, and content creators.
How it works
- Upload a screenshot of your app, website, or design.
- The engine immediately processes the image against 8 different color blindness matrices.
- Review the results to identify charts, buttons, or text that lose contrast.
Frequently asked questions
How common is color blindness in the real world?
Approximately 8% of men and 0.5% of women have some form of it. Deuteranomaly (weak green) is the most widespread, affecting roughly 5% of men.
Why is it vital to test my designs?
UX elements like charts, maps, status indicators (red=bad, green=good) that rely entirely on color can become unreadable. Testing ensures you use patterns or labels instead.
How scientifically accurate is the simulation?
It uses standard Brettel/Viénot-based approximation matrices widely accepted in professional accessibility tools, providing a highly accurate guide.
