I completely ignore chasing down the perfect color. Especially for topwater lures. My color choices across the board are fairly simple. Something dark, something bright, something natural. With topwaters, 90% of the time I really don't care. The action of the lure is FAR more important, IMO. I have seen days where I was throwing a standard Bronzeye, and my partner was throwing a Bronzeye popper, both in the same colors. The popper was receiving many more strikes. I noticed this and quickly made the switch to a popper in a different color. Instant action. Fish can see above the surface of the water, unless they're directly underneath the lure. Everything does become blurred somewhat, but silhouettes are visibile.
Don't put as much thought into color. Think more along the lines of lure action and noise levels.
