“BILL”是使用 FontVibe AI 创作的涂鸦文字效果。狂野风格的喷漆字母，带尖锐箭头和重叠造型，填满层叠的鲜艳色彩，粗黑描边锁边，红砖墙上还有颜料滴痕。

a wall coming alive with spray paint. PAINT: bold letters built up in physical layers of aerosol — a base fill, a thick load-bearing black outline holding the shapes, bright highlights and a 3D block shadow; paint drips run from the heavy spots, overspray mist haloes the edges, spray-can mottling and splatter droplets on the surface. COLOR: a full high-impact spray-can palette chosen for chromatic vibration — classic chrome-silver-and-black, electric blue, hot magenta, lime, orange, or multi-color fades — saturated for maximum punch at distance. GROUND: a real urban surface — red brick, grey concrete, a metal roller shutter or subway car — paint drips pooling below. LETTERFORM PRIORITY: when the chosen font carries its own treatment (wildstyle arrows, stencil bridges, marker handstyle, bubble, blockbuster, drips), that font treatment takes absolute priority and owns the letters; this style governs the spray layering, outline, drips, palette and the wall behind. FALLBACK MATERIAL: if the font carries no material of its own, spray the letters in layered aerosol with a thick black outline, bright fill, drips and overspray on a brick or concrete wall, so the graffiti energy always reads. A raw concrete wall dominates the frame, surface scarred with patches of older paint and ghost tags. 'BILL' explodes across it in a massive blockbuster throw-up, letters built up in thick physical aerosol layers — a blazing chrome-silver base fill with an electric blue-to-hot-orange gradient fade shifting across the forms, each letter locked in a heavy load-bearing black outline at least eight pixels thick, paint drips running fat from the bottom edges and pooling on the ground below. A crisp white highlight stripe cuts across the upper third of each letter, reinforcing the 3D block shadow that punches hard in deep charcoal to the lower-right, lifting the letters off the concrete surface. Overspray mist halos every letterform, spray-can mottling textures the fill, and a scatter of fine aerosol droplets hits the raw wall around the piece. Two thin metallic silver arrows flare outward from the terminal strokes, classic wildstyle flourish. Harsh urban midday side-light rakes across the concrete, throwing the embossed paint layers into sharp relief. Color: chrome silver, electric blue, hot orange, black, stark white. Saturated, maximum chromatic punch. Gritty, photorealistic street surface, no decorative borders or devices.
