My way of painting my DKoK army. Mostly so I can check if I forget what I did.
  Priming
 Prime with   Black Primer Prime with   Black Primer
Coat
- Airbrush   Dark Sea Blue  
 Cover most of the coat. Get the steel bits too.
 Airbrush   Anthracite Grey Airbrush   Anthracite Grey
 Aim only at the coat. This is the midtone.
 Airbrush   Grey-Blue Airbrush   Grey-Blue
 Aim only at highlight areas. Not too thick; shouldn't get to be the actual color.  Refer to photos taken after priming. Overdid it on the image. Will require glazing back in   Anthracite Grey
