I just don't think color is super important in plastics and most baits. I just try to find some spit up baitfish or crayfish and try to match colors of what they look like which usually tends to be green pumpkin, watermelon, brown/pumpkinseed, and white. I'll add a little JJ's for effect. I also hate owning tons and tons of different colors because it over complicates everythings. I will even throw these colors in muddy water (unless it looks like chocolate milk) because the baitfish and craws don't magically change colors because the water is dirtier. Sure, blacks and chartreuses stand out more but I seem to get bigger bites throwing more natural colors in dirty water.
However, I do think color is important in jerkbaits. I will throw 10 baits in 10 different colors and for some reason they will only want X bait in X color one day and a complete different one the next day
