Catching Shallow Water Walleye

We're running a chartreuse Flexi-Jig, and a black Flexi-Jig. The chartreuse has a blue Skooklie Minnow and then on the black Flexi-Jig a smokey sliver Skoolie Minnow. We're in about 9 feet of water and we're looking for the shallow-water walleye bite! Which color combo do you think will perform best?
