Back in the days(after someone suggested it) I did some initial testing using blue/silver instead of gold, but it looked kind of out of place and clashed badly with blood red especially. Maybe golden opulence and blood strikes a chord psychologically in a way that blue/silver and blood doesn't? Either way there wasn't a quick and easy way to make this work and since I'm quite happy with the current mood in Lunaris it is unlikely I'll try to change it again.
