I'm a fan of Green Pumpkin, but can only speculate what the Green and Brown variations are like. For the "plain", natural version, throw in Black flake, as others have said. If You handed me those 2 bottles of X2 and told me to make ONE Color, however I wanted, for a Craw/Creature bait...I'd use the GP Brown with a little .015" and .035"/.040" Navy Blue flake. GP Brown/Blue flake.
