This is my take on the colour scheme of Adharon's Reavers, a Chaos Space Marine warband featured in Forgeworld's Imperial Armour Vol. 13

The main colours are blue and silver.

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 Games Workshop spray cans and brush on paints.

Priming:

I find the metallic sprays from GW tend to be a little on the transparent side, so an initial undercoat of black helps.

1. Prime the model lightly with Chaos Black
2. Prime over that with Leadbelcher

Silver (Armour Trim):

1. Drybrush the model with Leadbelcher to even out the colour.
2. Shade the recesses and around any rivets with Nuln Oil
3. Highlight fine points and sharp edges with Stormhost Silver

Blue (Armour Panels):

1. Base with Caledor Sky
2. Shade the recesses with Nuln Oil
3. Highlight the edges with Teclis Blue
4. Highlight fine points with Lothern Blue
