Good link, thanks jchaos, hadn't seen that page before

I was thinking maybe a Khorne-based army with a red theme. The warriors/cavalry I might do with "iron" armour, black with a silver drybrush. Used to have some of those in 28mm years ago, a quick and easy paint job.
Not sure what colours for the young drakes yet, other than some shade of green, with maybe a yellow belly?
I'm waiting for an order for some Goblins and Burgunzian Flyers (DoW Birdmen). When I've got all that lot done, I might go for some Evil Giants to proxy for Ogres for both the Chaos and Orc & Goblin armies.
