“生抽”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. '生抽' dominates the composition, centered with generous breathing room in a square frame. Render the two characters as monumental matte primary-color forms: the first in signal red, the second in cobalt blue, each with a hard 45-degree isometric extrusion reaching down-right, pure black side walls at one-quarter character height. Faces are flat acrylic paint with absolutely zero sheen; edges are crisp, machined, and sharply separated from the black extrusions. Background is a stark white plaster architectural plane divided by an asymmetrical Constructivist arrangement: a cadmium-yellow horizontal bar cuts across the upper left, a tall black rectangle anchors the right edge, and a narrow cobalt-blue block sits low beneath the text. All color fields are perfectly flat, untextured, and aligned to a strict Swiss grid. A single cold-white overhead directional light casts ruler-sharp black geometric shadows directly below and slightly right of every character and plane. Head-on orthographic composition, no perspective tilt, no haze, no reflections, no organic detail. Bauhaus workshop clarity, severe graphic balance, high-contrast Chinese title mark.
