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.
