I know what you are talking about. At one time the rave was red hooks for perch fishing on Lake Erie. I tied some red flash on the collar of a gold aberdeen hook. Did it work? Yes or maybe for perch. Only thing when the perch get hot on feed they will hit practically anything and everything. Never tried it for crappie but I do not see why it wouldn't. It's just an attractor hollering " hey come over here and taste some meat!" I did some research and Grizzly Jig Company sells what they call a Tip-Its. Looks like feathers tied on a long shank straight eye hook.
