Everyone is going to give you THEIR favorite color combos. The fish, well they want what THEY want and that constantly changes with the conditions. A plain Minner works most of the time. It's ALWAYS the right color. The rest is trial and error. Anything and chartreuse is the best answer so far.
If you have boxes full of jigs, I guarantee you have the right colors. Figuring out those colors is the hard part on a tough day.
