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. Birthday party banner in use: 'Party Time!' rainbow bubble letters on a large fabric banner hanging on a brick wall at an outdoor birthday party. Colorful balloon bunches tied to sides. Tables below with birthday cake, confetti, decorations. Real outdoor party scene, warm afternoon sunlight. Rainbow bubble letters are vivid and clearly visible — exactly how users would display this in real life.
