Colored Hooks

[Bduck]

I keep a supply of red coated hooks in different sizes for replacement on lures. Catching a few fish on a set of red hooks using a pair of needle nose pliars removing the hook from the fish the coating tends to wear off of the hooks revealing its natural base, but the catch rate hasn't changed when I keep using this lure. Is the red coating there for the eye of the beholder to have a nice-looking presentation or do you think it really makes a difference to catching fish? If a lure has flash of chrome or copper/gold blades or even with reflective tape in many colors is that red coated hook making a difference? Most plug style baits purchased don't have a colored hook, but they do catch.
