See how a color appears to people with different types of color vision deficiency.
Types of color blindness
- ● Deuteranopia — Green cone deficiency (most common, ~6% of males).
- ● Protanopia — Red cone deficiency (~2% of males).
- ● Tritanopia — Blue cone deficiency (very rare, <1%).
- ● Achromatopsia — Total color blindness (extremely rare).
Why simulate?
Approximately 8% of men have some form of color blindness. Testing your palette ensures your charts, buttons, and UI elements remain distinguishable for all users. Use these swatches to verify accessibility.

Deuteranopia affects green cone cells, protanopia affects red cone cells, tritanopia affects blue cone cells, and achromatopsia is total color blindness where only shades of gray are visible. Each type uses different transformation matrices to simulate the visual experience.
Why should I test for color blindness?
Approximately 8% of men and 0.5% of women have some form of color blindness. Testing ensures your designs, charts, and UI elements are distinguishable by all users. This simulator helps you preview your colors through different types of color vision deficiency.
