I personlly like and recommend bright colors that allow you to not only see your arrow in flight but allows you to find your arrow more readily after the shot. I shoot both two white/one yellow and two flor. yellow/one flor orange....

Dark arrows don't do you any good to follow the flight of the arrow, see the arrow enter the deer, find the arrow after.

Go with bright fletch, stay away from dark or camo'd fletch...
