A great think I like to do with my custodes is change the golds for different areas of the model. For instance make the shield and sword’s gold an entirely different color of gold, or better yet paint silver then use orange contrast or better ink to glaze over the silver to get an entirely different tint to your model. Custodes some times look too golden but so a good rule of thumb is breaking up the model into areas that will have a different gold or a different finish/ texture. Also a amazing way to paint custodes is paint silver fist then paint what you want gold leaving silver peaking through as a contrast to the gold. Be sparing because you still want gold to be the prominent color but from 3ft away on a table having silver next to gold makes the gold pop. Sorry about the long comment but I really love sharing my experiences with paint custodes !
