The hook color won't really matter. I use bronze finished sickle hooks. It's the cheapest sickle hook and I don't have any better luck with red, black chrome, or gold hooks.

For where you get them, are you pouring them yourself or are you buying the plain jigheads from someone to tie on? If you're buying them made to tie on, PM GrouseFly, and there's quite a few other folks around here selling them. Just do a search or go back a page or two here in the jig tying forum.
