“MEST”是使用 FontVibe AI 创作的几何文字效果。包豪斯式大写字母，由圆、方与直线构成，平涂红、蓝、黄、黑，像实心积木一样立在硬朗顶光下。

Bauhaus geometric environment: hard overhead directional light — single cold-white source, zero ambient scatter, ruler-sharp geometric shadow edges below all forms. Background plane is architecturally flat: pure black void, deep matte concrete, or stark white plaster. No depth haze, no organic texture, no atmospheric bokeh. Scene vocabulary: Bauhaus workshop geometry, De Stijl primary-color planes, Constructivist poster surface, Swiss grid precision. Primary color atmosphere (always active): flat geometric primary-color planes — signal red, cobalt blue, cadmium yellow — appear as background architectural blocks or compositional color bars alongside the letterforms. Zero gradient, zero sheen. When no specific material is defined by the font: letterforms rendered with Bauhaus primary color flat-paint treatment — each letter one vivid matte hue cycling across the primary palette: signal red, cobalt blue, cadmium yellow, flat black. Hard 45-degree isometric extrusion with pure-black side wall, depth 25% of letter height. Flat matte acrylic surface, zero sheen. Sharp machined edge between color face and extrusion wall. Render the exact text "MEST" as the sole dominant typographic object in a Bauhaus workshop composition. Each character receives a flat matte acrylic face cycling through signal red, cobalt blue, cadmium yellow, and flat black. Apply hard 45-degree isometric extrusion to every letter, with pure-black side walls at approximately one quarter of the letter height; crisp machined boundaries separate every colored face from its black depth planes. Surround the text with architecturally flat De Stijl color blocks: a cobalt-blue rectangular plane, a cadmium-yellow bar, and a signal-red square, all with zero gradient, zero sheen, and exact-cut edges. Background is a deep matte charcoal concrete wall and floor register, marked by a faint orthographic Swiss-grid construction in dark gray. A single cold-white overhead directional source creates ruler-sharp black geometric shadows beneath the extruded forms and color planes, with zero ambient fill, zero reflections, zero haze. Head-on architectural camera, controlled shallow spatial recession, strict Constructivist poster balance, clean negative space, no objects, no people, no organic texture, no decorative elements.
