I've checked out the Core set for Dust tactics and see that both sides models come pre-coloured with grey and green to differentiate both sides. Personally, I appreciate that and it sort of has a toy soldier appeal to it. And I can't paint to save me. But I'm wondering with the other models that you buy seperately, do they have that colourization? Or are they all just generic pewter colour regardless of the side? This would help on my purchace decision, thanks!
