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. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the 24-karat gold metal, the hard directional key light and the dark void. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as bold 3D-extruded 24-karat gold with deep amber shadow recesses, rich warm gold faces and razor champagne-white speculars. COLOR PRIORITY: keep the font's own colors if specified; otherwise the warm amber-to-champagne gold range on a near-black ground. Create a finished, premium celebratory greeting graphic built around the exact Chinese text “贺信”. Set the two characters together on one generous line, large and centered, with ample breathing room around the compact composition; keep both characters fully visible, correctly formed, and unmistakably legible. Give the lettering the sole visual emphasis, with deep dimensionality and a substantial presence against an uninterrupted near-black void. Let the characters cast crisp, directional shadows down and to the right, grounding them in space while preserving clean separation between their forms. A very faint, restrained amber glow may gather directly behind the lettering to lift its silhouette without turning the background brown or competing with the gold. Add only a few delicate gold dust flecks close to the characters, sparse enough to preserve the dark negative space. Keep the arrangement symmetrical and composed, like an elegant formal congratulatory message, not a busy invitation or a scene with unrelated props. No extra words, symbols, borders, seals, or decorative objects. The result should feel prestigious, confident, and celebratory, with the two requested characters immediately readable at a glance.
