Personally I go through fazes where my jigs have to be 6 colors but most of the time I keep things simple. GP, watermelon, brown, black, and maybe some orange in the square cut silicone skirting. When I want a bulkier jig I use Starflash skirts in black, brown, or some combination on the two. My favorite big bass skirt material was called hydro and it is no longer available so the skirts I have left generally only come out when money is on the line.
