Purple-Blue-Green-Red-Yellow, in that order.
I use Green which are in the 5 to 7 inch range. TAKE NOTE! Not all brands are consistant in what they consider the proper size. Tom Browns' tend to run a bit large, Jerry's Bait tend to run what I consider the right size and Pacific baits' are on the smaller size. They all work fine. I don't plug cut for springers so I stay away from the blue label and as water flows lessen I will switch to red label to maintain the proper spin. Hope this helps.
