Hey, sorry dude, I've been stupidly busy lately which is why my activity has been somewhere between nothing and...Nothing. :lol:
If you still need help, personally if I were going for Salamanders I'd either use Orkhide Shake or Snot Green, if it's too dark for your tastes, get some white paint and mix it together to lighten it up, or is it another issue with the paint?
To be fair, the Salamander scheme has changed very little since the pre-heresy/heresy era, it was originally Chaos black with touches of green, but GW changed it to green overall, in a lighter sort of shade, I'd probably go for Orkhide Green for the right effect myself.
