I'll tell ya what I'd do :
I'd be throwing a 1/32 or 1/16oz marabou Roadrunner ... and not "at" the bank, but "along" the bank (+/-parallel) ... and after I caught several, I'd check to see if they were all males ... then I'd find the nearest dropoff/ledge and start throwing there, to see if the females were staging close by.
In water that shallow, murky or not, I don't think color would be a big factor. Anything pushing water is likely to be noticed.
If by "little ones", you were referring to the size of the Crappie ... it may be that the larger fish have already come & gone, as they sometimes tend to spawn according to size, with the larger fish coming in first, followed by the smaller/younger ones. But, there still could be some larger females staging, or even post spawn resting, out from those shallows. Even the females of the smaller/younger crowd would likely be bigger than the shallow males.
