In 30-some years of hunting, the color of my rifle has never made a difference in whether or not my hunt was successful. For that matter, I didn't even start wearing camo clothing until after I retired from the Army, trying to find a use for 20+ years worth of duds I didn't need for work anymore.

I think there are plenty of other things to spend one's time and money worrying about than camo - ammunition and range time for starters.
