My 2 cents...

There's two things to consider...

1. Does the hook color blend in with the lure?
2. Does the hook color blend in with the natural surroundings?

Consider the MS Slammer light trout. It has a white belly, so you might think white hooks would work. But the hooks hang down away from the bait, and if they were white you'd see big white things hanging off the lure, which wouldn't look natural. In this case the matte bronze hooks like gammie trebles look better since they fade into the background making it look like there's no hooks at all.

Baits like the Huddleston are more tricky. Most people rig a huddleston with two treble hooks stuck into the belly of the bait. With the hooks flat against the belly, they would blend in well if they are painted white. However looking at the bait from the right angle you still see white spears coming off the bait, which doesn't look so great.

Another option with the huddleston is black hooks. Black stands out less than painted white when sticking out away from the lure. But since the huddleston also has black tinged fins and black dots on the belly the black hooks will also not look out of place against the bait.

So basically if the hook is protruding from the lure I want it to be as invisible as possible... light wire and dull finish. If the hook is streamlined against the body of the lure then I want it to match the color of the lure. And even better if you can get both at the same time.
