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. “tosha” as joyful rainbow candy lettering, centered prominently with generous breathing room in a square 1:1 composition. Every individual letter contains its own complete vertical ROYGBIV gradient: vivid red at the top, flowing through orange, yellow, green, blue, and indigo to violet at the bottom. Keep every hue richly saturated, bright, and distinct; never assign one color per letter or let the rainbow run across the word as a single gradient. Give the letters a rounded, inflated balloon-like volume and an ultra-glossy candy finish, with crisp white highlights and soft colorful reflections across their surfaces. Background: a bright celebratory party scene with a warm golden-to-pink glow, softly blurred string lights, colorful balloons, and a light scatter of confetti around the edges. Warm sunlight from the upper right creates lively specular glints and gentle shadows beneath the letters. Keep the backdrop high-energy and colorful but softly out of focus, so the text remains unmistakably dominant and easy to read. The overall image feels playful, welcoming, and exuberant.
