I’ve had a couple of questions on this, so I’m posting my recipe for Madrak’s gold here:
I started with a base of Mud Brown (Vallejo Model Air). It’s not a dark brown, more of a caramel color.
Then I add pretty harsh (and sloppy if you’re going for this cartoony look) highlights with Lazur Yellow (Vallejo Model Air). It’s very creamy and light. Such a pretty color, lol.
Wash with Agrax Earthshade (Citadel wash).
Lastly, I add the extreme highlights with Lazur Yellow again, which will now seem brighter because we washed down the previous coat.
I’m sure there are other ways of doing it (especially if you’re trying for a more realistic look) but I’m pretty pleased with this. I was asked once how I got it to shine, so I hope that means I got close :)
Thanks for reading!
