See how colors appear to people with different types of color vision deficiency
Note: This simulation provides an approximation of how colors may appear to individuals with color vision deficiency. Actual perception varies by individual. Use tools like the Contrast Checker to ensure your designs are accessible.
FAQ
What is color blindness?
Color blindness (color vision deficiency) is the decreased ability to see colors or differences between colors. It affects about 8% of men and 0.5% of women of Northern European ancestry.
What are the most common types?
Deuteranomaly (green-weak) is the most common, affecting about 5% of males. Protanomaly (red-weak) and deuteranopia (green-blind) each affect about 1% of males.
How can I make my designs accessible?
Don't rely solely on color to convey information. Use patterns, labels, or icons alongside colors. Ensure sufficient contrast ratios (use our Contrast Checker tool).
Is this simulation accurate?
This is a mathematical approximation. Actual perception varies between individuals. Use it as a guide, not as a definitive representation of color vision deficiency.
