Well, the way I've been painting them is as thus, Black Undercoat, followed by two thin coats of Snot green, a wash with watered down black ink, followed by highlights of goblin green, the black parts of the Armour was chaos black, with highlights of an equal mix of codex gray and chaos black. and all the gold was done in brazen brass, with a wash of watered down chestnut ink, a heavy highlight of shining gold and a very fine highlight of mithril silver.
As for Salamanders, they have an abundance of Termie armour and Artificer armour, they also tend to have master crafted weapons, and their weapons of choice would be the Thunderhammer, flamer and melta weapons. and as the good baron said, A real lack of fast attack choises.
