During descent, which color is lost first?

Explanation:
Light is absorbed by water unevenly across colors, so as you descend colors fade in order of wavelength. Red has the longest wavelength and is absorbed first, so red is the first color you lose. As you go deeper, orange and yellow fade next, then green, with blue lasting longest and dominating the view at depth. That’s why, during descent, red disappears first.
