So bass kid, ince I'm too lazy to look it up, here is a question... When people say that red is the first color to disappear, does that mean that it turns to black or to what color? I've thought about the reasons why red snapper are red, and I wonder if their red color turns effectively black at a depth where there is very little light penetration ... so it makes the red snapper blend in well with an otherwise dark world?

To me the ideal hook color is still clear :)
