I don't know how to answer. The important ingredient is where you are fishing and what you are fishing for. In water that is fished a lot any strange color or shape may alarm the fish. Some fish don't seem to mind any noise or flash or bright line or dark line. They just want to eat. Others even a shadow of the rod or line will set them off. In general I try to wear neutral colors. But if a fish is forty feet away and you are out of its cone of vision what you wear doesn't make much difference. If you are fishing a tiny brook that is less than ten feet wide, anything you wear or do can affect the fish.
