「27」は FontVibe AI で作成したジオメトリックの文字エフェクトです。円、四角、直線で組み立てたバウハウス風の大文字。赤・青・黄・黒のベタ塗りで、硬いトップライトの下に積み木のように立ちます。

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. Create a finished Bauhaus-inspired event-poster composition built around the exact text “27.” Keep the numerals centered and dominant, occupying roughly three quarters of the canvas height, with generous, precisely measured negative space around them. Treat them as a monumental graphic object standing just forward of a flat matte charcoal concrete plane. Arrange strict signal-red, cobalt-blue, and cadmium-yellow rectangular planes around the numerals: a tall red block cropped at the left edge, a compact yellow square near the upper right, and a blue horizontal bar anchoring the lower field. Let these shapes create a disciplined asymmetrical balance without touching or obscuring the text. A single cold-white overhead light casts ruler-sharp geometric shadows beneath the numerals and color blocks, reinforcing their physical separation from the background. Keep the viewpoint frontal and the composition crisp, with clean margins and an unmistakable poster-like hierarchy. Use flat, unmodulated color fields and hard, exact edges throughout. No extra lettering, symbols, decorative texture, gradients, reflections, haze, or background clutter.
