i put a few of mine i want to fish with in a zip lock sandwich bag (mostly solid chartreuse, blue/chartreuse, and purple/chartreuse), put in a bit of virgin olive oil to keep them moist, and sprinkle them with fresh pepper and sea salt. The crappie seem to like the taste or smell or something. I never take more than 20 or so on any one trip so I don't spend all day changing colors.
