at times i dont think a painted head is any better than unpainted but a thing that i think helps at certain times is having a eye on the jig head i think that is pretty important to my observations but i do paint all my jigheads but they are all painted the same color two tone black and silver,all lot of the walleyes i have caught usually have a sheephead shad or some times a mooneye in there gut, these fish all have large eyes so it could help putting an eye on your jig.
