I misspoke... I have a lot of the regular GW paints, not many contrast.
This is what I came up with, it doesnt exactly match my priest grenades but I'm ok with it.
I'm not sure what the base was, but I think it was deathworld forest
Then nuln oil
Then drybrush elysian green
Going to do the metals next and grenades are finished
Base + wash on right / base, wash, drybrush left
