“3”是使用 FontVibe AI 创作的折纸文字效果。由珊瑚红、青绿、芥末黄和天蓝色纸折成的大写字母，折痕锐利、棱面分明地接住光线，置于干净白底上。

a clean origami paper-craft piece — crisp, geometric and cheerful. SURFACE / STYLE: the lettering looks folded from clean colored paper — sharp crease lines, angular geometric facets catching light at different angles, subtle shadow between the paper layers, a tidy hand-folded precision. SCENE ATMOSPHERE: a bright, clean paper-craft setting — soft even studio light, a few small folded paper shapes, calm uncluttered space. PALETTE: bright cheerful paper colors — coral, teal, mustard, sky blue and soft white — clean and crafty, with crisp facet highlights, never grungy or dark. LETTERFORM PRIORITY: when the chosen font carries its own treatment (origami fold, angular facet, geometric sans, isometric block, bold geo sans), that font's letterform takes priority and owns the letters; this style governs the folded-paper facets, the crease shadows, the clean studio light and the cheerful paper palette. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as crisp folded colored paper with sharp creases, angular facets and soft fold shadows, so the origami paper-craft feel always reads. A clean origami paper-craft mark built around the single numeral '3' — large, dominant, and bold, filling generous visual real estate on a bright uncluttered ground. The character is rendered as crisp folded colored paper with sharp crease lines running along each angular facet, subtle fold shadows nestled between the layered paper planes, and tidy hand-folded precision throughout. Soft even studio light rakes gently across the faceted surface, catching the highlights on each folded edge and casting delicate cast shadows onto the clean paper ground beneath. A few small origami shapes — a folded star, a tiny crane, a geometric pinwheel — scatter loosely nearby, reinforcing the paper-craft world without crowding the numeral. Palette: coral face, teal inner crease, mustard shadow facet, sky blue ground, soft white highlights on the sharpest fold edges. The overall feel is cheerful, geometric, and immaculate — bright paper-craft energy with crisp angular geometry and no grungy texture or dark shadow.
