The point is that any color can work as good as the next under the right lake conditions. Get comfortable using colors that work for you, but have others on-board ready to go if it's a day the walleyes are finicky, is smart. The blade size and lead length of harnesses may be important some days. A good tip is to have two of each color harness or different blade size with identical colors. This way you can run different size spinner blades or different lead lengths on tough days to experiment which works best.
Flexibility is important.
When lead length is important, cut and tie one harness with a 36 inch lead and the other 18 inches. If I had to pick one lead size to run under all conditions, it would be 24 to 27 inches. The best knot to use when making your loop at the end of your harnesses is a double figure-8 knot. Be flexible when using these rigs. They will work well once you get comfortable with them.
