Everyone says that red disappears at a certain depth, but one of the hottest colors for musky on our local waters right now is a bait color pattern everyone is referring to as strawberry. It is essentially red splotches over white.
On a hunch, I made one in all red and pink with no other colors on one my Flatshads. The guy that bought it emailed me to inform me that he caught three muskies the first day he used it and two more on the second day. Bear in mind, this is bait that is trolled at about 10 to 15 feet at what most fisherman would consider high speed.
I find they types of discussions interesting because I firmly believe there is still much to be learned about color when it comes to lures.
Take Firetiger for example. It catches fish big time. An amazing number of species respond to that particular color combination, yet, if you alter that pattern too much, the response rate drops off rather dramatically.
I believe there are still other patterns waiting to be "discovered" since many, if not most builders paint the same patterns as they see others painting. It reminds me of the days when I used to go walleye fishing...everyone would choose the same general area of the lake to fish because they'd look across the water and see a bunch of boats in one area and they' d join them...and no one would be catching fish.
I do believe, despite a lot of opinions to the contrary, that detail on a bait can make a difference, especially when one is painting the more natural patterns such as shad, perch, etc. Thus adding detail such a red near the gills, shadowing around the eye sockets, etc, make a bait that more properly matches the species being preyed upon.
