I don't know about hot colors but plain Gold, Pretty Panties, Pink Panties gold back, Purple Parrot copper back, Red Huckleberry copper back and Anti-Perch or any of the anti freeze color combination to name a few. I personally like Baitfish-Image Colorado blades in Rainbow and Golden Shiner from Northland Tackle in size 6 for trolling and size 2 for mayfly rigs. Blade colors will drive you crazy if you let them!
