“中铁十八局”是使用 FontVibe AI 创作的镂空喷绘文字效果。橄榄绿军用镂空模板大写字母，带连接桥断口和柔和喷溅边，喷在钉有金属护角的旧木箱板上。

Stencil spray application aesthetic — the visual language of pigment applied through a physical template onto an industrial surface. SPRAY MEDIUM: paint deposited through a cut template creates the defining edge characteristics — hard inner boundary where stencil material masked the surface, soft outer halo where overspray bled beyond the template edge. Paint density peaks at the center of strokes, thins toward periphery. Drip runs descend from areas of heavy paint application. The spray medium is matte and pigment-dense, completely unlike liquid or digital media. COLOR REGIME: maximum contrast two-tone palette — the stencil process is inherently binary. Primary combinations: black on concrete grey, military olive on weathered wood, white on rusted metal, warning red on industrial steel. The surface beneath always participates: substrate texture shows through thinner paint coverage, grounding the mark in physical space. SURFACE CONTEXT: stencil typography implies a physical surface — concrete wall, wooden crate, corrugated metal, canvas fabric. The substrate texture is visible through and around the paint layer, never a neutral void. Surface imperfections coexist naturally with the spray marks. When no specific material is defined by the font: default spray environment — matte black spray paint on rough concrete grey surface, visible overspray halo at letter edges, slight texture of concrete aggregate showing through paint. A rust-pocked corrugated steel construction-site barrier, layered with weathered industrial grey primer, oxidized seams, bolt heads, scratches, and streaks of dried rainwater. The rendered text “中铁十八局” is applied in dense matte warning-red spray paint through a physical cut-metal stencil, carrying crisp masked interior edges, narrow soft overspray halos, uneven pigment build-up, and fine steel texture visible through thinner areas of paint. Small breaks in paint coverage collect around ridges in the corrugation; several heavy sections release thin vertical drip runs. Cold early-morning fluorescent work lights rake across the barrier, catching rust flakes and casting shallow shadows inside the stencil bridges. Faint out-of-focus construction elements appear beyond the panel edges: galvanized scaffolding tubes, a concrete column, a suspended safety mesh, and pale dust in the air. The marking dominates the steel field with substantial visual weight and clear industrial legibility. Strict two-tone palette of warning red and weathered concrete-grey metal, with restrained dark charcoal shadows, documentary industrial photography, high-resolution surface detail.
