Hi Nao, Greetings from Malaysia...😘 My opinion is, I think Rough Gold would be the best choice. If so, you can try matte or glossy Orange color for basic@undercoat. Or maybe Red. Can't wait to see the result. See you again.
I have a question...how do you make the gold shiny like what primer surface do you recommend for make it shiny gold yellow-ish color...sorry i dont really know much about color and english is not my first language..sorry
