Same effect applies in golf. Why do you think they use white golf balls? The more "white" you use with your feathers or vanes, nock and etc., the better chance you'll have at seeing your arrow in flight. The human eye just picks it up faster and better. Try it, you'll be supprised at how often
you'll see the arrow in flight and strike the target. Helps to know how in tune you are with your setup too. Really neat to see the arrows fly like darts!
