I would say it depends on the head and skirt colors offered by the jig maker (I don't pay as much attention to the names). Colors such as Bama Craw (Junebug / Green Pumpkin) , Blue Craw , and a Green Pumpkin / Orange can work successfully for both imitating crawfish as well as bluegill . Also using a Green Pumpkin color jig and then altering the soft plastic trailer colors with Green Pumpkin , Orange , Brown , Blue , etc. can be effective to get you where you need to be . Choosing a dedicated Bream / Bluegill color jig is going to be more limiting as you definitely favor more of the Bluegill coloration and not a Crawfish with the Green Pumpkin / Blue / Orange / Yellow colors . Lastly , starting with a Green Pumpkin color variations in jigs as I shared above offers the most flexibility .
