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. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style always governs the color — every letter still carries its own complete top-to-bottom ROYGBIV rainbow gradient. FALLBACK MATERIAL: if the font carries no material of its own, render clean bold letters each filled with a full vertical ROYGBIV rainbow. COLOR PRIORITY: the rainbow gradient is mandatory and overrides any single font color — each individual letter is its own complete rainbow at full Pride-flag saturation. Birthday party feature-wall scene with the exact text "is turning" as dominant rainbow candy balloon lettering. Every individual letter contains its own complete vertical ROYGBIV gradient: saturated red at the top edge, orange through the upper body, yellow and green through the middle, blue and indigo below, finishing violet at the bottom; never distribute one color per letter and never stretch one rainbow across the full phrase. Each letter has rounded inflated volume, seamless candy-gloss skin, crisp reflected highlights, soft contact shadows, and tiny white rectangular reflections from nearby party lights. Surround the lettering with floating helium balloons in hot pink, chrome gold, cyan, cherry red, and violet, plus curled metallic ribbons and scattered paper confetti in Pride-spectrum colors. Behind it, a bright birthday venue wall fades from warm coral to sunny yellow, with dense strands of fairy lights rendered as circular golden bokeh and translucent rainbow light flares. Warm late-afternoon sunlight enters from one side, producing glossy specular streaks and clean luminous edges. High-chroma celebration palette, polished commercial party invitation render, ray-traced reflections, sharply readable text, no extra words, no logos, no dark backdrop.
