“BLOCK”是使用 FontVibe AI 创作的3D 立体粗体文字效果。厚重的方块大写字母带深度挤出，每个字母一种亮面糖果色，顶光让高光滚过圆润边角，彩色倒影落在地面上。

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. A modern design agency presentation room — clean white walls, warm overhead track lighting, a wide-format print mockup pinned to the presentation wall. The print mockup shows a toy brand product packaging front panel: "BLOCK" as the product name in massive colorful 3D candy-surface block letters, centered on the packaging, filling 60% of the panel width. B cherry red, L electric blue, O sunshine yellow, C lime green, K hot orange — ultra-glossy lacquer surfaces catching natural directional specular reflections from the track lighting above. Letters cast clean parallel shadows on the print surface. The mounted print has a subtle surface sheen. Agency office background softly bokeh. Presentation wall and packaging print are sharp focal point. 16:9 professional design workspace scene.
