It IS similar, but the Half & Half figure wasn't quite the colour I was after. I actually have a piece of dyed cloth fabric I was trying to match to. I couldn't sleep last night, so I went back & gave it another try.
I managed to finally "achieve" the colour I was looking for at last. I found it (as everyone suggested) after thin coats of Scorpion Green followed with washes of Thrakka, & Golden Yellow dry-brushed on after. I feel my dry-brushing has improved a little, if nothing else.
