“StarGirl”是使用 FontVibe AI 创作的彩虹文字效果。绚丽的多彩虹色渐变文字特效，色彩过渡顺滑，棱镜般的光泽与欢快的多彩排版。

rendered as rainbow text effect — COLOR (mandatory): each individual letter must contain a complete ROYGBIV rainbow gradient top-to-bottom within itself — top=red, upper=orange, mid=yellow-green, lower=blue-indigo, bottom=violet. NOT one color per letter. NOT a gradient across the whole word. Every letter is its own complete rainbow. Full chroma Pride flag saturation — not pastel, not muted, not shifted to any single hue. Beauty brand packaging mockup: 'StarGirl' in holographic rainbow letters on a cosmetics product — a sleek black lipstick or eyeshadow palette box. Holographic iridescent text catches studio light and creates rainbow color play across the packaging. Other beauty products visible in background, soft studio lighting.
