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. Rainbow granite text rendered as rainbow candy balloon letters — each individual letter a fully inflated spherical 3D balloon with ultra-glossy candy lacquer surface, complete ROYGBIV gradient contained within every single letter top-to-bottom: red crown bleeding into orange, yellow-green mid-band, blue-indigo lower body, violet base. NOT a gradient across the full word — each letter is its own complete rainbow. Maximum Pride flag chroma saturation, zero pastel shift. Background: sunlit granite quarry environment — rough-hewn pale grey granite slabs with coarse crystalline texture filling the background, warm directional sunlight raking across the stone surfaces at low angle creating deep shadow pockets in the rock grain, scattered mineral flecks catching specular highlights like embedded glitter in the stone. Warm golden ambient fill bounces off the granite faces and back onto the balloon letter surfaces, adding a honey-toned rim glow to the violet and red bands. Brilliant white specular hotspots on the uppermost curve of each balloon letter catch the overhead sun. Loose confetti scatter in primary colors drifts at the lower foreground plane, soft-focus. Depth of field blurs the mid-ground granite slabs into smooth stone-toned bokeh discs, keeping full sharpness on the balloon letters. Octane render, ray-traced subsurface gloss, 8k.
