I get the sense, from reading your posts, that you're suffering from the same malady as myself and, honestly, a lot of other people -- there are just so many options.
And, while that's not a bad problem to have, it's still a problem if you let it be.
I'm gonna let you in on a secret: There are two colors that will work in every single body of fresh water that contains bass.
Black w/blue flake (or Junebug, if you swing that way)
Green Pumpkin
If you never buy another color of jig aside from those two, you're gonna be okay. I get really fancy with swim jigs. For swim jigs, I'll add two more color options:
White w/chartreuse (to emulate crappie or baitfish like shad)
Green pumpkin w/orange and chartreuse (to emulate bluegill)
Those four five jig colors will cover just about every situation in which you'll want to have a jig tied on.
But what, I hear you asking, about trailers? There are so many! Trailers can be just as easy, and in the same colors (black w/blue flake, junebug, green pumpkin, white, chartreuse).
Strike King 4" Rage Craw (or equivalent) for when the fish want a lot of movement
Strike 4" Menace (or equivalent from another brand) for when the fish want a little more compact presentation, but still want nice movement
Reaction Innovations Sweet Beaver (or equivalent) for when the fish are lethargic or are especially spooky
Strike King 3.75" Rage Swimmer (or an equivalent paddletail swimbait) for swimming a jig
Zoom 4" Fat Albert (or an equivalent curly-tail grub) for just about any situation
When you're ready, go on over to Siebert Outdoors and order you some jigs. You can get soft plastics for trailers, too.
Do yourself a favor and quit fretting the details. This is supposed to be fun.
