Different colors become invisible at various depths due to light absorption:
- Red: Disappears at 15-20 feet (4.5-6 meters)
- Orange: Visible until 25-30 feet (7.5-9 meters)
- Yellow: Visible until 35-45 feet (10.5-13.5 meters)
- Green: Visible until 70-75 feet (21-23 meters)
- Blue: Penetrates deepest, visible beyond 100 feet (30 meters)
This phenomenon explains why deep-sea creatures often appear red – in their natural habitat, red appears black, providing excellent camouflage. Clear water and good visibility conditions can slightly extend these ranges.
