An informative article from 1996 by Dr. Colin Kageyama, an Optometrist, who discusses what happens to colors underwater. Dr. Colin describes the differences between the color red, and flourescent red. As colors fall lower in the water column, there are some things that happen to specific colors, that aren't commonly understood.

These color changes are relative to how close you are to the lure, as well as the color and turbidity of the water itself. This information helps anglers choose what lures to use depending on the conditions and depth of the water.
