The only thing where color matters IMO is contrast to a background, whether sky, sideways in the water column or bottom.
I could show you many pictures of many fish caught on many colors in different waters - many on the same day and in the same water.
Today I poured clear mini-sticks and I guarantee they will catch fish especially now that the water is cooling and getting clearer. That's pretty much the minimum visual contrast needed for a fish to take interest and the lure's action does its stuff.
Each lure I make will work in just a few colors or one color and I don't need to carry more, but lure action and shape are priorities ; color may enhance both.
Clear lures in clear water makes good sense to me. The fish can sense movement via lateral line, but have a harder time seeing it. Thus, they are probably slower to identify it as a fake. Even if caught, they will likely not condition as rapidly to avoid a lure they never see clearly.
