According to the manufacturers they sell more worms in these colors:
Watermelon-can be used in clear or stained water either one.
Pumpkin-used in moderately clear to stained water.
Junebug-stained water but has been used successfully by some pros in clear water. One of my favorites.
Red Shad-Stained water worm, when I had my tackle store I sold more of these than any other color.
Tequila Sunrise-Stained to muddy water and also great for night fishing.
A decade ago the metallic worms were the fad but now more and more anglers seem to be switching to the natural colors. The manufacturers say black and purple colored worms are selling less and less. I personally have caught most of my bass on a purple color worm.
