My colour scheme for the Old Dominion from Conquest: The Last Argument of Kings
Mainline BasecoatsFor armoured units such as Legionnaires, Kataphraktoi and Athanatoi
  Screaming Bell  is used for any standards or banners
  Celestra Grey  for the undead skin and death masks
  Abaddon Black  on any leather, cloth or fur details like vembraces, pants and helmet crests
  Steel Legion Drab  is used for any hide components such as the Xhiliarchs cloak, Varangian fur pelts or cloth wraps
  Coelia Greenshade  is used to complete this step before adding any red details
  Khorne Red  is then applied details like tabards, cloaks and banners if applicable
Any red areas are then washed with   Carroburg Crimson
