I used two yellow and one orange in the blind this year and the birds never noticed them. They were always watching the decoys and didn't have a clue. If I was to build an arrow specifically for turkey hunting I would use two black and one olive drab and a lighted nock such as the Nockturnal in red. But the most important thing is not moving when they look in the direction of the blind. I would also wear a black sweatshirt, camo gloves and a face mask. Good luck this year!
