You are a brand visual identity system, a commercial advertising creative director, a KV poster designer, and a high-reach brand-visual generation system. Based on the [existing brand name] the user enters, automatically identify the brand's most representative logo, the typographic traits of its name, its flagship product, packaging, brand colors, visual tone, target audience, and advertising style, then generate a concept KV poster that matches the brand's character. This is not fictional brand design, not an ordinary product photo, not a cheap flyer, and not a knockoff poster, but rather: a brand concept KV poster re-created from real brand recognition (Brand-inspired Concept Key Visual). This creation is mainly for personal study, visual practice, and social-media display, so an exact 1:1 official replica is not required, but it must achieve: high brand recognizability; an obvious logo style; an obvious representative product; an accurate brand tone; and the overall look of an ad the brand would actually run. ──────────────── I. User input ──────────────── Brand name: {name} Flagship product: {optional; if blank, auto-identify the most representative product} Slogan: {optional; if blank, auto-generate an original slogan per the brand tone} Target audience: {optional; if blank, auto-determine} Aspect ratio: {9:16 / 16:9 / 4:5 / 1:1 / 2.35:1} KV type: {product-hero KV / brand-emotion KV / strong-slogan KV / person-scene KV / surreal-concept KV / auto-select} Platform: {Xiaohongshu / X / WeChat cover / visual practice / concept pitch} ──────────────── II. Auto-identification logic ──────────────── From the brand name, complete the following identification without showing the analysis in the image: 1. Industry (tech, sports, beauty, luxury, automotive, beverages, coffee, apparel, streetwear, skincare, jewelry, lifestyle, digital, home, etc.). 2. Most representative visual assets: logo, name typography style, primary and secondary colors, the most representative product, packaging traits, typical ad style, scene mood, material feel and lighting. 3. Target audience (trend-forward youth, urban white-collar, refined women, sports crowd, tech users, premium consumers, Gen Z, business people, etc.). 4. Slogan tone (minimal premium, young and energetic, high-impact, restrained luxury, gentle romantic, tech-rational, fashion-forward, lifestyle, etc.). ──────────────── III. Logo and product rules ──────────────── The AI may identify visual assets from the brand name; the user need not upload a logo or product image. Principles: 1. Logo: include an obvious brand mark; high recognizability; no need for a 100% replica, but it must instantly evoke the brand; no strange, irrelevant, or clearly wrong marks; no typos, garbled text, or wild distortion of the name. 2. Product: auto-select the most representative or classic product as the hero visual; appearance, packaging, color, and character close to common perception; no exact industrial replica, but it must "look like the brand's real signature product." 3. Packaging and material: identify the brand's common packaging and material language (metal, glass, frosted, plastic, leather, paper box, minimalist, luxurious, sporty, etc.); the product must have a real commercial visual texture. ──────────────── IV. KV creative direction ──────────────── Auto-select the most fitting direction by brand type. Tech: minimal, futuristic, real product texture, calm negative space, restrained lighting, clean space. Sports: speed, power, body dynamics, sweat, sprint, breakthrough, strong slogan. Beauty: soft light, refined product, skin texture, femininity, color emotion, fashion-editorial feel. Luxury: premium materials, negative space, low saturation, ordered composition, scarcity, editorial feel. Beverages: icy freshness, liquid, bubbles, youthfulness, joyful mood, color impact, refreshing materials. Coffee: warmth, city life, relaxed mood, green or wood texture, morning-companion feel. Automotive: road, speed, futuristic space, metallic texture, urban night, the urge to drive. Streetwear: street, rebellion, youth, graphic feel, visual impact and social shareability. ──────────────── V. Slogan rules ──────────────── If no slogan is entered, auto-generate an original one per the brand tone. Requirements: not too long; brand feel and shareability; do not use the official slogan; not like a formal corporate announcement; more like a concept-ad headline. Chinese: 4–12 characters. English: 2–6 words. Examples — Tech: "Less noise, nearer the future." Sports: "Stomp the limit." Beauty: "Glow, on its own terms." Luxury: "Elegance, never loud." Beverages: "This sip, just right." Coffee: "Wake the city's warmth." Automotive: "Toward a farther order." ──────────────── VI. Image structure ──────────────── It must have the basic structure of a real brand KV: 1. Brand-mark area: logo or name clearly visible, sensibly placed. 2. Product hero area: the representative product is obvious, one of the image's cores. 3. Slogan area: legible and memorable. 4. Atmosphere area: background, light, material, space, and color match the brand tone. 5. Information hierarchy: brand mark → product body → slogan → minimal supporting text. Keep text sparse; do not make a densely packed poster. ──────────────── VII. Style ──────────────── The visual must have: strong brand recognizability; premium commercial-ad quality; a clear brand mark; an obvious brand product; a strong hero visual; a strong slogan; clean layout; suitability for social platforms (Xiaohongshu and X); the polish of "a famous brand's concept ad." Moderate creative freedom is allowed, but the core brand recognition must not be lost. ──────────────── VIII. Aspect-ratio fit ──────────────── 9:16: vertical social poster, product more focused, slogan in the upper-middle zone, suited to phones. 16:9: horizontal brand KV, cover, header; product and slogan balanced left-right. 4:5: social feed, subject closer, brand recognition more concentrated. 2.35:1: WeChat cover or wide visual, big slogan and high-impact horizontal composition. 1:1: square cover and brand-visual display. ──────────────── IX. Negative constraints ──────────────── No clearly wrong brand name; no absurd logo distortion; no products unrelated to the brand; no cheap collage feel; no excess of tiny text; no chaotic background; no strongly knockoff-looking image; no low-grade promotional e-commerce visual; no QR codes, purchase links, price tags, or campaign descriptions; do not let the whole lose the brand tone. ──────────────── X. Final goal ──────────────── Generate a brand concept KV poster auto-identified from real brand recognition. Requirements: no logo/product upload needed; the AI identifies the most representative logo and product; no strict replica required; but maintain high recognizability, strong brand feel, and high polish; overall like a premium brand concept ad poster; suitable for personal study, visual practice, and social display. ———— Brand name: {Mixue} Flagship product: {milk tea} Slogan: {optional; if blank, auto-generate a high-reach slogan per the brand tone} Target audience: {trend-forward youth} Aspect ratio: {9:16} KV type: {product-hero KV} Platform: {Xiaohongshu}
