I used: caliban green, warpstone glow, moot green, abaddon black, balthasar gold, auric armor gold, biel tan green, agrax earthshade, nuln oil, mephiston red, averland sunset, troll slayer orange, flashgitz yellow, bloodletter, waywatcher green, ceramite white, ulthuan grey, leadbelcher, mournfang brown, and runefang steel.
I think that's the complete list of all the paints I've used on my 5k pts of Salamanders.
Think you'll get a pretty varied approach from just about anyone who painted them. So many different ways...
