Seeing Colors Differently

Most people pick out red, green, blue and yellow easily. In some people’s eyes certain colors blend together, and a few people see no color at all.

In the picture

  1. Bowl of fruit in panel one: red, green and yellow as most eyes see them
  2. Traffic light in panel two: the red and green lamps look muddy brown
  3. Blue cup in panel three: blue and yellow fade away while red stays bright
  4. Bowl of fruit in panel four: every piece is a shade of gray

Examples

  • Finding ripe strawberries in a green garden is hard when red and green look alike.
  • Matching clothes or socks sometimes needs a friend’s help.
