It should be easy enough to work out which ones you need for which part, if not then you can watch the vid and he'll say when he uses each one. The green seems to be just two colours, Dark Green and Scorpy Green. He's a great guy with great videos, well worth subscribing too. Might have other salamander vids, not sure this was just the first that came up.
