rendered as hyper-glossy 3D inflated forms — smooth candy lacquer surface with a strong circular specular highlight at each convex peak. Vivid Y2K candy color palette: each letter independently colored in saturated bubblegum pink, mint green, electric lavender, or sky blue. Soft ambient occlusion in the deep crevices between letters. Gentle soft drop shadow below, slightly blurred. Playful volumetric depth from studio overhead key light. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the glossy inflated 3D form, the candy lacquer surface and the overhead key light. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as hyper-glossy inflated 3D letters with a strong circular specular highlight at each convex peak and candy-lacquer surface. COLOR PRIORITY: keep the font's own colors if specified; otherwise give each letter a vivid Y2K candy hue (bubblegum pink, mint green, electric lavender, sky blue). Render the exact text “say boo to the flu” as a playful seasonal health-awareness graphic with hyper-glossy inflated 3D letter bodies. Give each character an independent saturated Y2K candy hue: bubblegum pink, mint green, electric lavender, sky blue, with occasional citrus orange accents. Apply smooth candy-lacquer surfaces, crisp circular white specular highlights at every convex peak, subtle translucent edge glow, and deep soft ambient occlusion in the narrow crevices where inflated forms meet. The phrase has clear hierarchy through scale contrast, with “boo” carrying the largest visual weight and the remaining words supporting it in a compact rhythmic arrangement. Surround the lettering with small floating cartoon ghost shapes made from pearly white glossy vinyl, tiny lavender germ-like spheres with soft spikes, and miniature glossy orange pumpkins; keep these secondary elements sparse and clearly separated from the words. Set against a smooth midnight-indigo to violet gradient backdrop with faint misty cyan halos and scattered star-like bokeh dots. A diffused overhead studio key light creates rounded volume, with gentle blurred drop shadows beneath the letters and props. Clean high-resolution product-render finish, ray-traced reflections, polished playful October campaign aesthetic.
