rendered as rainbow text effect — COLOR (mandatory): each individual character 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 character. NOT a gradient across the whole text. Every character is its own complete rainbow. Full chroma Pride flag saturation — not pastel, not muted, not shifted to any single hue. Create a joyful, polished party poster with the exact words “SO MUCH FUN” as its unmistakable centerpiece. Arrange the words on three centered lines, with “FUN” largest and most prominent, “SO” above it, and “MUCH” between, leaving clear breathing room around every word. Make the lettering feel like a buoyant celebration feature, hovering just in front of the scene, with subtle depth and soft shadows that keep it distinct from the background. Set the composition at a bright outdoor summer celebration beneath a luminous blue sky, with warm golden sunlight, delicate lens flares, and colorful out-of-focus festival lights. Surround the words with a lively but carefully controlled scatter of tiny confetti pieces and a few floating balloons in vivid complementary colors; keep all decorations behind or around the lettering, never covering it. Add soft sunlit bokeh toward the edges and a gentle burst of color behind “FUN” to draw the eye inward. Keep the background bright, richly saturated, and uncluttered, with strong contrast around the words and generous clear space so the exact phrase reads instantly at thumbnail size. The overall image should feel exuberant, welcoming, and ready to share as a party invitation.
