How common is color blindness?

About 8% of men and 0.5% of women have some form of color vision deficiency. Red-green color blindness (protanopia and deuteranopia) is by far the most common type.

How do I test for color blindness in my design?

Upload your design to the Color Blindness Simulator or use Chrome DevTools' vision deficiency emulator. Check each simulation type to verify that all information is understandable without relying on color alone.

What colors are safe for color-blind users?

Blue and orange are generally distinguishable across all types of color blindness. Avoid red-green combinations for critical information. Always pair color with icons, patterns, or text labels.
