This is my take on the paint scheme of the Shrouded Hand warband, a splinter group of the Alpha Legion featured in the Chaos Space Marine codex from 8th Ed. 40k.

The main colours are green 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 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):

I generally start with the armour trim so that any time I get paint on another piece its easy to cover later.

For grenades, replace Nuln Oil with Athonian Camoshade

1. Drybrush over 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
4. Add a rust effect sparingly with thinned Skrag Brown

Green (Armour Panels):

1. Base with Kabalite Green
2. Shade the recesses with Nuln Oil
3. Highlight fine points and sharp edges with Sybarite Green

Purple (Details - Cloth, Wraps):

1. Base with Naggaroth Night
2. Shade the recesses with Nuln Oil
3. Highlight the edges with Xereus Purple
4. Add fine points of Pink Horror

Gold (Details - Buckles, Chaos Icons, Weapon Details):

1. Base with Retributor Armour
2. Shade the recesses with Agrax Earthshade
3. Highlight fine points and sharp edges with Stormhost Silver

Black (Details - Armour Ribbing):

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

Brown (Details - Leather Pouches):

1. Base with Rhinox Hide
2. Shade the recesses with Agrax Earthshade
3. Roughly highlight the edges with Skrag Brown
4. Add a fine highlight of Skrag Brown

Red (Details - Lenses):

1. Base with Mephiston Red
2. Shade the recesses with Agrax Earthshade
