Massive chunky 3D block letters with heavyweight extruded presence — thick uniform extrusion depth of 50-60% of letter height. Front face finished in ultra-glossy lacquer, catching directional key light with natural specular reflections that graduate from bright highlight to deep saturated color — the surface quality of hard candy coating or high-gloss toy paint. Side extrusion planes in a noticeably darker shade of the same hue, creating crisp face-to-depth contrast that reads immediately as three-dimensional volume. Adjacent letters each carry a different vivid saturated color, maximizing chromatic contrast across the word — no two adjacent letters share the same hue family. Hard sharp corner edges where face meets extrusion, no beveling. Long dramatic cast shadows at consistent 45-degree angle, shadow depth approximately 40-50% of letter height. Strong directional key light from upper left. Bold, high-contrast, maximum visual impact. 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 glossy 3D extrusion, the directional lighting and the multi-color scheme. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as thick glossy extruded 3D blocks with hard candy-lacquer faces and darker extrusion sides. COLOR PRIORITY: if the font specifies its own colors, keep them; otherwise give each adjacent letter a different vivid saturated hue. Massive colorful 3D block letters centered in frame, filling 75-80% of width. Each letter in a different vivid saturated color — ultra-glossy candy lacquer surface with bright circular specular highlight at center, darker extrusion sides clearly visible. Long parallel cast shadows at 45 degrees. Strong key light from upper left. Background: deep dark studio with rich atmospheric depth — subtle color gradients from warm amber to cool blue, faint volumetric haze, hints of environmental color bleed from the letters. Polished dark floor below letters showing clean mirror reflections of each letter's color. Camera: frontal view, slight low elevation. Letters fill the frame with commanding presence.
