Here is my advice, and it may be somewhat different. First, it doesn't mateer to me what color my fletchings are, that is overrated IMO. I prefer white (I use four fletch arrows, so I use all one color) when there is no snow so I can see the color of blood easily. In the snow, I'll usually use a flourescent color along with the white, but that is to make arrow recovery easy, not to see the arrow in flight.

When I am shooting at game, I concentrate on the target only, I don't worry about seeing the arrow in flight, there is no need to at all. If you keep the concentration on the game, you will see the point of impact every time (except in low light conditions). Usually, I will not see the fletchings or the arrow, but will see the hair move where the point of impact is. The same is true when using a gun. If you concentrate on your target, after the shot you will see where you hit.
