Real quick - the populace badge for the Kingdom of Atlantia is a blue unicornate seahorse named Spike.
So I did.
I foresee a can of transparent blue enamel paint in my future. And some gold-colored wire and a touch of solder.
EDIT: On second thought, probably not transparent enamel. It'll show up as green with the gold behind it, won't it? So opaque blue, but I'll try and make sure the twisted wire ornaments are clean of it.
