I would have thought Ayleid gold, but thankfully there are helpful threads showing that it is virtually identical to Dwarven Brass, which I have and is much warmer in tone than the Silyanorn Ayleid gold items.
So far, the best I’ve found is Material 3 on materials which dye like metals but it varies. It might work but there are yet quite a few dyes that I don’t have and unfortunately there is no way to preview them, so I thought I’d ask and see if anyone else had recommendations (with screenshots appreciated)!
