For bluegill and crappie, my default starting color is red. Our Motor Oil color is reddish (not greenish like some others) and a close second. Blood Red and Orange almost always work. Also been selling lots of Bubble Gum and use it alot myself. Crappies seem to love it. Notice a pattern... all have red in them.
Here's my take on some other colors but each lake is different. Experiment when they are biting, to see if your bites increase or decrease. Use 2 identically rigged poles down the same hole and see which one gets more bites.
Pearl/White - Best dark/night crappie color Black - Great picky crappie color Purple - Real good all around - Perch seem to favor it. Yellow chartreuse - Perch in a stained flowage!
Off topic - in the summer I drift with 1/32 oz jig and the Whip. Bubble Gum, Yellow chartreuse, red, purple all work great. Side note - was drifting with Lindy rigs and leaches for walleyes. Spilled the leaches under the floor boards of the boat. Put a full purple Whip on the Lindy Rig and got 2 keeper walleyes! You never know.
Keep experimenting and Good Fishing! Chris
