RE: Fletching colors ?
 

Two black and one orange here with an orange nock. I prefer to take the middle ground. Too many bright colors and the deer can see them. Too few and you have a difficult time following the arrow's flight/entry point on the animal as well as a difficult time finding the arrow on the ground afterwards.

RE: Fletching colors ?
 

The brighter the better ! I like all white with white crown. I made some up the other night I call my "sissy" arrows. Hot pink ezecrest fades with 2 hot pink fletch and 2 chartreuse.

Do NOT use those on a 3D course - they are an arrow MAGNET :D
