Hey, for a quick method I (although this is a khorne warrior mind) painted armour mechrite red, washed with badab and highlighted with blood red.
Fur and boots (and other brown bits) was painted with calthan brown and drybrushed with graveyard earth, boots highlighted with graveyard earth.
black stuff highlighted with codex grey
all metal areas except chainmail, was painted with boltgun metal and washed with badab
Chainmail painted with you guessed it, chainmail

and washed with badab
Bone areas was bleached bone and wash of devlan mud
Tried to use as little number of paints as possible
What mark has been given to your warriors?
Sorry this is a bad pic and ok paintjob I think.
