Color blindness, or color vision deficiency, affects approximately 1 in 12 men (8%) and 1 in 200 women (0.5%) worldwide. It is primarily a genetic condition, though it can also result from eye, nerve, or brain damage, or exposure to certain chemicals.

Types of Color Blindness

Color blindness is typically categorized into three main types:

• Red-Green Color Blindness - The most common type, including:
  • Protanopia/Protanomaly: Reduced sensitivity to red light
  • Deuteranopia/Deuteranomaly: Reduced sensitivity to green light
• Blue-Yellow Color Blindness - Less common:
  • Tritanopia/Tritanomaly: Reduced sensitivity to blue light
• Complete Color Blindness - Very rare:
  • Achromatopsia/Achromatomaly: Unable to see any colors

Designing for Color Blindness

When designing websites, applications, or visual content, consider these best practices:

• Don't rely solely on color to convey information
• Use patterns, shapes, or labels in addition to color
• Ensure sufficient contrast between text and background
• Choose color combinations that work for color blind users
• Test your designs with color blindness simulators

This simulator helps you understand how your images and designs appear to people with different types of color blindness, allowing you to create more inclusive and accessible visual content.
