Plastic Grub Worms/Colors?

[Michael Loebbaka]

Hello. I am new to the fishing world. I’m learning here and there from research and getting out there to my local community lakes in Tucson, AZ. I’ve mostly been fishing for Catfish or Trout; Bass on the other hand, I learned takes a different technique. I have some 2-3 inch Berkeley grub worms and I hear good things about them, especially for catching Bass. 
 

I have different colors of plastic grub worms and would like to know each of my colors purpose for fishing certain water conditions. I have green chartreuse, white, black, and pumpkinseed. My local community lakes in Tucson, AZ seem somewhat greenish/clear water. Any tips or types of colors anyone recommend?

Time to show my chart again, if there is a dominant forage for the location then pick a color that looks like that (reminder: this is a GENERAL chart, not the end all be all, there are countless examples of catching fish using the "non-recommended" color).
