“RUBBLE / SAND / STONE”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 demolition-site barrier, coated in concrete-grey dust and scraped bare along raised ridges, with bent seams, old bolt holes, shallow dents, and pale mineral stains. Render the exact text “RUBBLE / SAND / STONE” as three separate stencil markings, each word divided by a painted slash, in dense matte black spray pigment. The paint is applied through a physical cut template: crisp masked inner edges, broken bridges and cutout gaps, granular pigment buildup at stroke cores, soft charcoal overspray halos beyond the stencil boundaries, and scattered dry-spray specks across the steel texture. Thin vertical drip runs descend beneath the heaviest black-painted sections. Weathered steel remains visible through uneven low-density areas of pigment. Harsh low-angle daylight rakes across the corrugations, producing narrow shadow bands, bright abrasion highlights, and deep grooves filled with dust. At the frame edges, out-of-focus fractured masonry, torn caution tape, and a small accumulation of crushed stone establish an active demolition yard. Restricted two-tone palette: matte black, oxidized brown-red steel, concrete grey, and chalky beige dust. Photorealistic industrial surface study, high-resolution texture, shallow environmental depth, no additional words, no logos.
