A way of creating a pale non-metallic for stormcasts using a limited color palette.
The end result of this paint for the gold ends up being fairly pale, to reach a more golden saturation consider adding some red / orange or yellow depending on the hue you would like to target.
Build up layers by adding more Golden Brown If transistions are too harsh feather down to a warm color with Golden Brown and even more to a cool color with Payne's Grey (Pay attention to where you want your light source and hills and valleys of the model.)
Edge highlight with mixes of Golden Brown and Bold Titanium White building up your edge layers.
Create scratches with Warm Brown lines and Bold Titanium White above the line.
