>I know Vallejo Metal is great too but I don't remember if they have a good gold.
they dont, its too greenish and pale, they also have just one copper

you can make do if you follow vince's advice and mix gold+copper+gsw gold pigment, the result while it may be realistic is a bit more desaturated than usual gold colors, i wouldn't recomend it
pic rel is that mix with a very thin vallejo smoke (iirc) wash on it
