Design Implications for Color Blindness

❌ Problematic Patterns

  • • Red/green error/success indicators
  • • Color-only information conveyance
  • • Low contrast complementary schemes
  • • Subtle color variations for critical data

✅ Accessible Alternatives

  • • Icons combined with color coding
  • • High contrast monochromatic schemes
  • • Texture and pattern differentiation
  • • Multiple visual cues for status
