完整提示词
[BRAND NAME]. A high-end conceptual leather clutch designed in the exact shape and silhouette of a classic disposable paper lunch sack (rolled top, rectangular base, NO HANDLES). The object is floating weightlessly in the center.
**CRITICAL SHAPE & FORM:**
The object must mimic a folded paper lunch bag. It has jagged/crimped cut edges at the top opening. The top is rolled or folded over casually. It must NOT have any handles or straps.
**CREATIVE COLOR PALETTE & BRANDING:**
The AI must act as a color stylist. Do not default to standard brand colors. Generate a unique, bold, fashion-forward color combination.
* **Bag Color:** A vivid, unexpected luxury tone (e.g., Electric Lime, Deep Ultraviolet, Burnt Orange, or Cobalt Blue).
* **Logo Size & Color:** A **medium-sized, centrally placed** `[BRAND NAME]` logo is deeply embossed on the front. Do NOT make the logo huge or oversized; keep it proportional and elegant with plenty of negative space around it. The logo is stamped with a highly contrasting color (e.g., White logo on Blue bag) to make it readable.
**MATERIALS:**
Ultra-premium, soft-grain calfskin leather that mimics the crinkles and folds of paper. Hyper-realistic leather texture.
**ENVIRONMENT & BACKGROUND:**
A seamless, perfectly clean, pure white studio cyclorama background. High-key brightly lit environment.
**LIGHTING & ATMOSPHERE:**
High-key editorial lighting. A strong backlighting setup creates a glowing "light aura" (halation) around the edges of the bag against the white background. The edges are slightly blown out.
**CAMERA:**
Medium format, 100mm lens, f/5.6. Slight shallow depth of field (sharp logo, soft back).。提示:增加表面纹理描述(如「细微颗粒感」「丝绸光泽」)可以拉满细节层级。
