“REBEL”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 premium streetwear brand shopping bag on a clean urban surface — natural daylight, clean background. The paper shopping bag front panel prominently features "REBEL" as the brand name in bold 3D block letter style — R electric yellow, E hot orange, B cherry red, E electric blue, L lime green — printed with full 3D depth and glossy lacquer finish on the kraft paper surface, filling 65% of the bag front panel width. Paper bag texture and bag handles visible. Street culture brand identity packaging. Shopping bag and printed brand name are sharp focal point — 16:9 streetwear brand packaging scene.
