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. “DIWALI” as the unmistakable hero, centered in a balanced 1:1 composition with generous breathing room. Every individual letter contains its own complete vertical ROYGBIV rainbow gradient: vivid red at the top, flowing through orange, yellow, green and blue into indigo and violet at the bottom. Keep every rainbow full-spectrum and richly saturated, never pastel, never one color per letter, and never a single gradient running across the whole word. Give the letters a joyful, fully inflated balloon presence with candy-gloss surfaces, rounded dimensional volume, crisp edges, and brilliant warm specular highlights. Surround the word with a bright Diwali celebration: glowing rows of small oil lamps along the lower edge, scattered flower petals and a few delicate sparks of light, with colorful festive lights dissolving into warm golden bokeh behind it. Use a luminous amber and saffron atmosphere with touches of magenta and turquoise in the distant decorations; keep the background bright, celebratory, and uncluttered so the rainbow lettering remains dominant and perfectly legible. Soft golden light from above and to one side catches the glossy curves, while gentle shadows beneath the letters give them depth. Radiant, festive, and full of welcoming holiday joy.
