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. Render the exact text “Planes 3°A” as inflated candy-gloss balloon lettering, with the words and characters carrying clear hierarchy through scale and spacing rhythm. Every individual letter, numeral, degree symbol, and A must contain its own complete vertical ROYGBIV gradient: saturated red at the top edge, orange through yellow and green across the upper-to-middle body, blue and indigo below, ending in vivid violet at the bottom edge. Never distribute one hue per character and never run one rainbow across the entire phrase. Use smooth spherical inflation, translucent lacquer depth, tight curved seams, bright white specular highlights, subtle reflected color bands, and realistic helium-balloon volume. Place the typography within a sunlit airport festival setting: a clean bright cyan sky, soft cream clouds, distant runway shimmer, tiny blurred aircraft silhouettes, rainbow pennant strings, and scattered metallic confetti. Add warm golden-hour sunlight grazing the glossy surfaces, crisp rim highlights, multicolored lens flares, and soft bokeh from terminal string lights. Keep the background bright and airy so every rainbow character remains sharply legible, high-chroma, and physically dimensional. High-resolution commercial event key art, ray-traced reflections, polished candy-plastic finish.
