Metallic color

[Abyssal Designs]

Hi Greg,
Yes, I already tried but doesn't look real, also in ray trace I put the colors as a predefine metal (bronze,copper,brass)and the color is completely different from the one I want it. those turn out to be what the metal originally is if is copper turn more like red if is brass turn out like brown/yellow but what if I want regular purple color with some metallic finish
Thank you for your help
