Create an ultra-premium narrative beverage poster for COSTA COFFEE Orange Grapefruit Refreshing Black Coffee, designed in the same visual campaign series language as the previous storytelling beverage posters: a highly realistic hero drink placed at the lower center, with a poetic flavor-memory world rising upward from the drink itself. The whole image should feel like a flagship editorial beverage advertisement, emotionally atmospheric, visually striking, highly art-directed, and clearly part of the same premium series, while shifting the main color identity into a new Costa-specific citrus-red direction. Series consistency: keep the same overall campaign structure and visual rhythm as the previous beverage posters: - one highly realistic hero drink at the lower center - a rising visual plume made of aroma, mist, flavor, and storytelling imagery - elegant editorial typography on a clean premium background - soft narrative atmosphere, collectible poster quality, refined emotional tone The new poster must feel like another page in the same beverage campaign series, not a different design direction. Main composition: a highly realistic cup of COSTA COFFEE Orange Grapefruit Refreshing Black Coffee sits at the lower center as the absolute hero product. The beverage must look commercially believable, premium, and sharply realistic. Use a transparent cold cup or refined clear takeaway cup with accurate modern café proportions, subtle COSTA COFFEE branding, visible lid or clean open-cup styling, realistic ice cubes, dark black-coffee base, bright orange-grapefruit infusion glow, translucent citrus slices, peel twists, delicate condensation, glossy reflections, and believable interaction between coffee depth and citrus freshness. The drink itself must remain photographic, crisp, cold, and appetizing. Drink realism: the COSTA drink must feel like a true fruit-black-coffee special: - deep transparent black coffee or dark amber-black base - citrus orange and ruby-grapefruit tonal glow - clear ice refraction - realistic grapefruit flesh and orange peel accents - subtle infusion gradients between fruit brightness and coffee depth - authentic condensation droplets - premium branded cup realism Do not stylize the beverage into fantasy. The drink must stay grounded in real commercial beverage photography. Storytelling visual: from the top of the drink, create a soft rising visual plume made of citrus aroma, cool mist, coffee vapor memory, watercolor-like fruit haze, and poetic awakening atmosphere. Inside this plume, build a layered narrative world that expresses grapefruit freshness, orange brightness, black coffee clarity, urban energy, and cool summer alertness. The upper visual should feel like flavor turning into atmosphere and memory, not a literal collage. Narrative imagery inside the plume: - grapefruit groves and sliced ruby grapefruit glowing in sunlight - orange peel spirals, drifting zest particles, citrus mist - subtle coffee-origin references such as coffee branches, roasted beans, warm aroma trails, café memory - one or two poetic human moments, such as someone taking a first cold sip during a city morning, or a refreshing break in soft afternoon light - warm and cool contrasts suggesting both black coffee sharpness and fruit freshness Everything must blend upward organically from the drink, like aroma and flavor transforming into visual storytelling. Visual impact: the poster should feel vivid and premium, with stronger contrast between dark coffee tones and bright grapefruit-orange energy. Use luminous citrus haze, suspended droplets, glowing zest particles, and a more sculpted rising plume, while keeping the composition elegant and not chaotic. Color distinction: this poster must clearly separate itself from the previous Starbucks and NESCAFÉ versions through a new dominant palette: ruby grapefruit red, coral orange, fresh citrus peach, deep coffee brown-black, COSTA burgundy undertones, warm cream background, subtle blush-pink highlights, restrained botanical green accents. The palette should feel fresh, juicy, modern, and premium, while still belonging to the same storytelling poster series. Background: mostly clean warm ivory or lightly textured premium paper-like background, with generous negative space and soft editorial calm. The drink and rising narrative plume should dominate. Keep the layout clean and sophisticated. Typography: integrate refined artistic typography in both English and Chinese, beautifully composed like a premium editorial beverage poster. Use elegant serif mixed with clean modern sans-serif, with graceful spacing and hierarchy. Include text such as: “COSTA COFFEE” “Orange Grapefruit Refreshing Black Coffee” “橙柚清爽黑咖” “FROM BITTER TO BRIGHT” “每一口，都是黑咖与柚香的清醒共振” Typography must feel luxurious, airy, and designed, not crude bold default fonts. Mood: fresh, bright, refined, sophisticated, awakening, citrus-driven, modern, premium, emotionally resonant, like a high-end café concept poster that turns a fruit black coffee into an atmosphere and a sensory memory. Lighting: soft premium daylight mixed with crisp beverage-commercial highlights, subtle glow through the liquid, realistic reflections on the cup, gentle but defined shadow below the drink, luminous ruby-citrus glow inside the rising plume, polished editorial poster lighting. Style: ultra-detailed, premium beverage advertising, realistic product photography fused with poetic storytelling art, editorial poster design, elegant campaign continuation, subtle watercolor aura, high-end COSTA COFFEE visual language, 8K, masterpiece. Negative prompt: generic menu poster, unreadable COSTA logo, cartoon drink, fake liquid, unrealistic cup shape, messy citrus collage, oversaturated red-orange, ugly typography, crude Chinese font, low resolution, plastic-looking fruit, muddy coffee color, cluttered background, flat lighting, watermark
