I painted the gold areas with a 50/50 mix of Dark Brown and Shining Gold as a base then followed with a pure Shining Gold layer, next a wash of Ogryn Flesh a tidy up with Shining Gold. The final gold highlights with Burnished Gold then a few strokes of Mithral Silver on the upper most edges.
The Tactical Arrow symbol that I cut up to look similar to the roman numeral two worked out pretty well after it was painted up.
Hope you enjoyed watching this model come together as much as I did. I really like the colour scheme!
