I have some tubes like that and some of the Netbait worms I toss Water jelly, table rock red, and sun perch are layered worms and I do really well with them. I have never really thought about if I had a worm that was one of the colors of the layered worms how would it do. I think with the laminates you are trying to match some sort of prey with the two colors. It is an interesting thought. I am surprised that a few years back when northland came out with the slurpies tube they had a layered perch, Shad, and craw were the colors I bought and they worked great, but they were discontinued pretty quickly. Not sure if people didn't buy into the concept or if they wouldn't buy bass baits from a historically walleye company.
If I think of it while I am on the water this summer I may experiment a bit with this, but not try to overthink it, because I would then carry way too many colors in the boat lol.
