I have found that lure colour does not make much difference. It's the action that makes the difference. Try slowing down your retrieve or putting more action into the lure. I find that just twitching the tip of the rod works most of the time. Are you fishing for them in shallow water, deep water or snags? If you are able too, try sight fishing for them. (and any other speices actually) It will give you an idea of how the lure is performing and what actions affect the fish in what ways. Practice makes perfect....
