“ECHO”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. Clean origami paper-craft title treatment for the exact rendered text “ECHO”. The hero word is formed from layered folded paper planes in coral, teal, mustard, sky blue, and soft white, with every letter surface divided into crisp angular facets. Fine scored crease lines run across the paper geometry; alternating facets catch soft studio highlights while recessed folds hold narrow, pale gray-blue shadows. Build subtle depth through raised paper layers, clean cut edges, visible fold intersections, and tiny ambient-occlusion seams beneath overlapping panels. Surround the lettering with a sparse paper-craft environment: a few miniature folded cranes, diamond folds, and triangular paper offcuts resting on a matte soft-white paper backdrop. Keep the field uncluttered, with generous clean negative space and no printed texture, dirt, wrinkles, ink, devices, or photographic props. Soft even studio illumination from above and slightly across the scene, diffuse contact shadows, controlled facet contrast, sharp clean edges, premium handcrafted paper model photography, high-resolution ray-traced material detail. The word remains the clear visual priority, with rhythmic color changes between its folded planes and bright highlights along selected creases.
