Loss of color underwater at depth
What color disappears first underwater?
Water absorbs different wavelengths of light to different degrees. The longest wavelengths, with the lowest energy, are absorbed first. Red is the first to be absorbed, followed by orange & yellow. The colors disappear underwater in the same order as they appear in the color spectrum. Even water at 5ft depth will have a noticeable loss of red.
At what depth underwater does color disappear?
- Red - 15ft
- orange - 25ft
- Yellow - 35-45ft
- Green - 70-75ft
