Color Blindness Simulator
Simulate how colors appear to people with different types of color vision deficiency.
What types of color blindness does this simulate?
This tool simulates Protanopia (red-blind), Deuteranopia (green-blind), Tritanopia (blue-blind), Protanomaly (red-weak), Deuteranomaly (green-weak), and Tritanomaly (blue-weak), plus Achromatopsia (total color blindness).
How accurate is the simulation?
The simulation uses established color transformation matrices based on scientific research. While not perfect for every individual, it provides a good approximation of how colors appear to people with each type of color vision deficiency.
Why should I test for color blindness?
About 8% of men and 0.5% of women have some form of color vision deficiency. Testing ensures your designs, charts, and interfaces are accessible to everyone.
What is the difference between -opia and -omaly?
-opia (like Protanopia) means complete absence of that cone type, resulting in total inability to distinguish certain colors. -omaly (like Protanomaly) means reduced sensitivity, causing colors to appear muted but still somewhat distinguishable.
