Many many years ago, when I first started painting minis, I used Ral Partha paints. I was quite happy with them at the time, but of course they have long since been discontinued in North America (I think you can still get them on their website, but you certainly can't buy them locally in any hobby shops!).
Anyway, one metallic colour they used to have was a brassy one. I don't know if it was their "Old Gold" or "Bronze" - there are no colour swatches for the metallics on their website (but I think it was Bronze?).
It was a really nice colour, with a dark golden sheen and a hint of green, just like real brass. GW metallics never had anything like it. Does anybody know of any equivalent in other ranges in North America? I hate to buy online for things as small as one pot of paint, so I go buy locally when I can. I have access to places that sell P3, Tamiya, Vallejo, maaaybe Humbrol? (I think?) Oh and GW of course. Maybe a few others I'm forgetting.
