Best colors for Ringworms,Super Doo,K Grubs

I usually fish crappies, this year I’m thinking about trying to catch walleye on the Mississippi. I hear a lot about Ringworms, Super Doos and K grubs. I picked up a few at Gander Mnt, but was wondering what colors should be “must have” in my tackle box.

white for sure, chartuse, cotton candy, purple

I would not go on the water during early Spring without Ringies/Ks/SDoos in: firecracker, cotton candy, chartruese pepper, chartruese orange core, chartreuse green core, oyster shell,purple/white tail and Stewarts Pro blue. The brighter colors will be more and more effective as the water clarity continues to deteriorate.

Thanks for the replies, ordered a bunch of them today along with some H2O jig heads. May need some help on how to on Pool 13. Maybe have to head up river to where all you “pros” are and get some pointers.
