Mine are more-or-less standard, with a few changes. I went for Warlock Purple with a purple ink wash, Codex Gray drybrushed over black for the "metal" bits and Brazen Brass for the gold trim (thought the gold paint was a bit too bright). A bit more reddish-purple than what's often used, but closer to the earlier series darkish pink Primus colouring I think.
I have seen pretty nice black-and-gold and even Russian-style 3-tone blue camo paint jobs.
