This is my take on the Brazen Beasts warband colour scheme featured in the Khrone Daemonkin codex from 7th Ed. 40k.

The main colours are gold, crimson, and a dark bronze.

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 lightly with 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 with Agrax Earthshade
3. Highlight fine points and sharp edges with Stormhost Silver

Bronze (Armour Panels):

1. Base with Warplock Bronze
2. Shade the recesses with Agrax Earthshade
3. Highlight fine points and sharp edges with Balthasar Gold

Red (Details - Shoulder Pads, Head, Cloth):

1. Base with Mephiston Red
2. Shade the recesses with Agrax Earthshade
3. Highlight the edges with Evil Sunz Scarlet
4. Add a fine highlight with Wild Rider Red
5. Highlight fine points with Fire Dragon Bright

Brown (Details - Leather Pouches, Wraps):

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 with Ushabti Bone

Black (Details - Armour Ribbing, Weapon Casings):

1. Base with Abaddon Black
2. Highlight the edges with Eshin Grey
3. Highlight fine points with Dawnstone

Silver (Details - Weapons, Grenades):

For grenades, replace Nuln Oil with Athonian Camoshade

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

Green (Details - Lenses, Eyes):

1. Base with Caliban Green
2. Shade the recesses with Nuln Oil
3. Layer the middle with Warpstone Glow
4. Add fine points of Moot Green

Molten Weapon (Details):

Layer towards the outside, leaving the inner portions a lighter colour

1. Base with Dorn Yellow
2. Layer with Yriel Yellow
3. Add a thinner layer of Fire Dragon Bright
4. Layer less with Wild Rider Red
5. Add a thin layer of Khorne Red
6. Roughly blot the edges with Abaddon Black
