I've witnessed on more than one occasion where one color seems to outshine the other for whatever reason. Apparently it can make a difference. Case in point, last year my son and I were fishing together with four rods a piece. I sat and watched him catch 11 crappie to my 1 on a Southern Pro minnow tube with an orange colored jig head. This color worked great until lunch time. After lunch he didn't get a fish on it. The depth and way we were fishing didn't change. We started catching fish on other colors and I eventually caught up with him.
Can't let the little guy think he can outfish his dad. lol!
