Bump. Second go 'round at finding out what paints the dakka community thinks were used to achieve the pictures on page 18-24 in the Codex:
CSM.
I'll add Dark Wolves to the list.
Alpha Legion: Enchanted Blue and Snot Green ?
Apostles of M: mostly the lighter Blood Red, huh?
Dis of Destruction: Gotta be Warlock Purple
World Eaters: Which red?
How about the PLague Marines on page 72? There's no way that is the same Rotting Flesh I just bought, unless I'm really color blind.
