I wondered when someone would point that out.

Yes, I did focus on how color changes with depth. I forgot to add how water clairy effects color. It does. I don't have the info at hand, but there is a "chart" that tells what colors are better in different clarities / colors of water. I do remember that fish don't see greens and blues very well in algae filled water, so when there is an algae bloom in Lake Erie, lures wtth a lot of green and blue don't show up well. Or, fish don't see them very well, at least the colors on the lure. Assuming the lure is at a depth where the algae is present in significant enough concentrations.

If I remember I'll find that "chart" and put the info here.
