you really can't go wrong with using Chartreuse, for either or both head/tail. :D
Just IMHO .. were I looking for jigs in these body colors : these are what I'd be looking for ---
For the two browns ... white head, chartreuse head, pink head -- orange tail, chartreuse tail, red tail (in combinations that mimic bugs or crawdads)
For the green - flo green head ... flo yellow or charteuse tails (sunfish pattern)
For the orange ... orange head, red head, chartresue head -- chartreuse tail, dark green tail, brown tail, white tail (totally unnatural and off the wall, for those fish that have seen it all :p )
This is just a "suggestion", for what it's worth ... and not an order :D (I'm going to have to live another 60yrs, just to use up all the jigs I already have ... LOL!!! )
