24-karat gold metallic surface — three-tone spectral gradient: deep amber-brown in shadow recesses, rich warm gold on lit faces, razor-thin champagne-white specular lines where direct light strikes. Single hard key light from upper-left at 45°, casting crisp directional shadows to lower-right. Background: near-black with faint warm amber ambient glow. No colored tints — pure dark void that forces the gold to own all luminosity in the frame. Square 1:1. A premium matte black ceramic coffee mug on a dark stone coaster, product photography. Side of the mug: 'METAL' printed in gold foil — warm gold letter faces, amber-brown where the foil follows the slight curve of the ceramic, champagne-white specular line catching the studio key light from the upper-left. The mug has a slight glaze sheen around the gold lettering. Steaming coffee visible inside the mug. Cold studio light, soft shadow to the right. Lifestyle product carrier — gold lettering on branded merchandise ceramic.
