This is a Homebrew chapter trying to mix elements of the Iron Warriors with the Emperor's Children.

The main colours are brass, purple, silver, and green.

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 with Chaos Black
2. Prime over that with Leadbelcher

Silver (Armour Panels - Except for the Shoulder Pads)

1. Drybrush over with Leadbelcher to even coverage
