This is my take on the Corpsemakers Nurgle-aligned warband featured in the Death Guard codex for 8th Ed. 40k.

The main colours are tan and a oxidized copper.

General Information:

My general method is to lay down all the base colours for the model, then do all the shading in the recesses before moving on to the highlights.

I don't own an airbrush, so the recipe will mainly consist of brush on paints.

Priming:

Prime the model with Wraithbone

Copper (Armour Trim):

1. I generally start with the armour trim so that any time I get paint on another piece its easy to cover later.
2. Base the trim with Balthasar Gold
3. Shade the recesses and around rivets with Agrax Earthshade
4. Add an oxide layer selectively with thinned Incubi Darkness
5. Add a small layer of Kabalite Green allowing the Incubi Darkness to show through
6. Highlight fine points and sharp edges with Stormhost Silver

Tan (Armour Panels):

1. Base with Ushabti Bone
2. Shade the recesses with Agrax Earthshade
3. Highlight the edges with Screaming Skull

Black (Details - Armour Ribbing, Weapon Casing, Cables):

1. Base with Abaddon Black
2. Highlight the edges with Eshin Grey

1. Base with Leadbelcher

Dark Pink (Details - Wraps, Cloth, Tassels):

1. Base with Screamer Pink
2. Shade the recesses with Agrax Earthshade

Brown (Details - Leather Pouches):

1. Base with Rhinox Hide
