This is my take on the Night Stalkers warband colour scheme featured in the Chaos Space Marines codex from 4th Ed. 40k.

The main colours are a pink tinted grey, with gold and green accents.

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 grey helps.

1. Prime the model with a light coat of Mechanicus Standard Grey
2. Prime over that with Retributor Armour

Gold (Armour Trim)

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

1. Drybrush over the model with Retributor Armour to even out the colour
2. Shade the recesses and around any rivets with Agrax Earthshade
3. Highlight fine points and any sharp edges with Stormhost Silver

Pink-grey (Armour Panels)

1. Base the areas with Rakarth Flesh
2. Shade along the recesses with Agrax Earthshade
3. Add a thin coat of Carroburg Crimson into the recesses
4. Add a thin highlight of Pallid Wych Flesh along the edges and around the inside of the armour trim allowing the Carroburg Crimson to show through

Black (Details - Armour Ribbing, Tubes)

1. Base with Abaddon Black
2. Highlight the edges with Eshin Grey
3. Add a fine highlight of Dawnstone

Green (Details - Cloth, Weapon Wraps, Tabard)

1. Base the area with Incubi Darkness
2. Shade the recesses with Nuln Oil
3. Highlight the edges with Kabalite Green
4. Fine highlight of Sybarite Green to points and sharp edges

Silver (Details - Weapons)

1. Base with Leadbelcher
2. Shade the recesses with Nuln Oil
3. Highlight the edges and sharp points with Stormhost Silver

Brown (Details - Leather Pouches)

1. Base the areas with Rhinox Hide
2. Shade the recesses with Agrax Earthshade
3. Roughly highlight the edges with Skrag Brown
4. Add a fine highlight of Ushabti Bone along the edges allowing for some Skrag Brown to show through

Beige (Details - Horns, Teeth)

1. Base with Rakarth Flesh
2. Layer the lower half with Skrag Brown
3. Shade over with Agrax Earthshade
4. Highlight the upper half with lines of Rakarth Flesh
5. Add fine points of Pallid Wych Flesh
