I'm a crappie FREAK..... in truth 99% of the time char/black. If its after a cold front blue/white the rest of the time if they don't hit those two go home

. With that said black /pink mostly in the summer..... blue/char all year but spring is a go to color...... orange/char is good some times. Purple combos are good as well. I find when the fishing pressure is up than my custom made color will out fish anything because they have never seen it before.
I think With crappie shapes make more of a difference than any thing
Spring 3/4-1 3/4 tubes and stingers
Summer 2 -2 1/2 carrots and paddle tails.... this is when paddle tails shine!
Fall 2 tubes and 2.5 carrots
Winter 2.5 -4 inch carrot or any BIG profile bait
That is based in the shad life cycle on our lakes. Might be different place to place but in Missouri you can take that to the bank.
