“KAI”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 wide 16:9 graffiti mural of the name 'KAI' dominating a long concrete wall, sprayed in a bold multi-color fade with drips and overspray, gritty street daylight. Raw wildstyle mural energy, no devices.
