Purple is a remembered color Kyle. I'm thinking the old "grape" was another. I don't recall them using chartreuse but back then everybody and their brother was stuck on chartreuse twister tails, at least those that used plastic on walleyes then. The Lindners pretty much brought plastic into the walleye domain. At the time there was little in the way of panfish plastics but the did exist and bass anglers of course were already tied into plastics. Basically the Lindners took bass plastics and very pointedly fished them well outside of the arena by chasing walleyes and sauger with them. That concept is still being expanded today. The solid purple, or grape [Florida grape? or midnight blue? in the X2 line] still make outstanding walleye/ sauger bait colors.
