“五七班”是使用 FontVibe AI 创作的霓虹光效文字效果。青色与品红交替的圆润霓虹灯管大写字母，灯管芯明亮、光晕柔和，在黑暗中把彩色倒影投在湿地面上。

rendered as real bent glass neon tubes with visible tube brackets and mounting hardware. Bright cyan and magenta neon light, sharp glowing edges with soft light bloom, visible glass tube refraction. Slightly uneven brightness between letters for realism. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the glass-tube neon material, the glow bloom and the color. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as real bent glass neon tubes with visible brackets, glowing with sharp edges and soft bloom. COLOR PRIORITY: keep the font's own colors if specified; otherwise bright cyan and magenta neon. Render the exact text “五七班” as a physical neon installation on a damp, weathered dark-brick school corridor wall after evening rain. Each character is formed from continuous bent glass neon tubing, with exposed tube joints, clear acrylic standoffs, small chrome mounting brackets, cable clips, transformer box, and discreet wire routing visible against the mortar lines. Alternate saturated cyan and hot magenta illumination across the characters, retaining slight irregularity in tube brightness and tiny hotspots at the bends. Sharp internal glass refraction, pale phosphor cores, and layered colored bloom spread across the midnight-blue brick surface. A narrow rain-slick concrete ledge and wet tiled floor catch fragmented cyan-and-magenta reflections, softened by shallow puddles and fine water droplets. Keep the surrounding environment near-black navy rather than pure black, with faint indigo haze, brick chips, damp stains, and cool reflected light revealing material texture. The glowing class name is the sole practical light source, casting colored edge light onto brackets, wires, wet wall texture, and pavement. High-detail photorealistic nighttime sign photography, ray-traced glass, realistic neon exposure, controlled soft bloom, crisp tube edges, cinematic low-light contrast.
