Understanding Color Blindness

Color blindness, or color vision deficiency (CVD), affects approximately 8% of men and 0.5% of women worldwide. It's important for designers and developers to consider these users when creating visual content.

Types of Color Blindness

• Protanopia/Protanomaly: Difficulty distinguishing between red and green colors. This is the most common form of color blindness.
• Deuteranopia/Deuteranomaly: Another form of red-green color blindness, where green appears more red.
• Tritanopia/Tritanomaly: Rare condition affecting blue-yellow color discrimination.
• Achromatopsia: Complete absence of color vision, seeing only in shades of gray.

Design Tips for Color Blind Accessibility

• Don't rely on color alone: Use patterns, textures, or labels to convey information.
• Ensure sufficient contrast: Use our contrast checker to verify text readability.
• Test your designs: Use tools like this simulator to check how your designs appear to colorblind users.
• Use colorblind-friendly palettes: Avoid problematic color combinations like red-green or blue-purple.
• Provide alternatives: Offer text-based alternatives for color-coded information.
