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. 'ARCOS' rendered as inflated candy-gloss balloon lettering, each individual letter containing its own complete vertical ROYGBIV spectrum: saturated red at the top, orange through upper sections, yellow and green across the middle, blue and indigo below, deep violet at the base. Every letter has rounded pneumatic volume, seamless heat-welded contours, mirror-bright white specular streaks, subtle translucent vinyl depth, and crisp reflected highlights. Surrounding atmosphere: a sunlit outdoor Pride celebration with a clear cyan-blue sky, soft warm lens flares, distant rainbow fabric banners, and clusters of glossy helium balloons in pink, gold, red, turquoise, and violet. Fine multicolored paper confetti drifts through the air, with scattered reflective foil pieces catching sunlight. A field of warm festival string lights dissolves into circular golden bokeh behind the lettering. High-chroma color separation, clean bright exposure, ray-traced glossy reflections, sharp hero lettering against a softly defocused celebratory background, polished 3D advertising render.
