Yes sir, I have found several color variations for the desert southwest, I did use mass produced colors as a starting point but tweaked the colors over the years, some are fairly close variations while others literally I have had people laugh at until they see how they catch fish.
5 different variations of the 1.5 just with paint, total about 20 different variations of the same bait with finish, snap rings and hooks.
Sometimes it was as easy as just lightening up a color or 2 on a bait, Other times very bold colors instead. One of the main differences that I do is fade/feather my paint into the next color and add a highlight overall that can only be seen at direct angles.
I am always pushing the limits of the baits with weight, multiple coats of finish, split rings and hooks size.
