Cool Roof Festival

Produce a 3:4 event poster for “Cool Roof Festival,” aimed at ordinary community participants. Use roofing color swatches rising into a cross-section of urban temperature to explain the event, prioritizing real seams and load traces over decoration. Organize the artwork through an asymmetric vertical composition, using negative space only to strengthen the metaphor. Read “Cool Roof Festival” first, followed by “Leave one observation for the next visitor” and “the north hall of the former waterworks / check in ten minutes early.” Use no malformed characters. Treat directional arrows, handwritten slips, and material samples as evidence for the hero. Preserve woodcut linework on warm cotton paper texture and divide rain blue, ink black, paper white, and rose red into dominant, supporting, and accent roles. Reveal material thickness through a hooded overhead lamp. Reflected light only opens dark structure, and shadows never conflict. Show only the placard, with essential information protected from trim. Use no brand, celebrity, IP, HUD, QR code, or luxury display shortcut. For the final rendering, show the metaphor through a single controlled metamorphosis: roofing color swatches rising into a cross-section of urban temperature. Preserve a believable scale, allow gravity to influence every loose edge, and give the nearest contact point the sharpest shadow. Use empty space as part of the rhythm, leaving the final information line uncompressed. Final art direction: editorial poster design with a disciplined grid and material-aware composition. Use this controlled palette as the dominant visual system: #F2EBDD, #243447, #C65D48, #D6A14B; preserve believable local material colors within it. Preserve the requested text hierarchy and wording as part of the design, but do not invent extra slogans, pseudo-text, logos, or watermarks. Keep one unmistakable primary subject or information route and one readable visual action. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, material thickness, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No unrelated decorative icons, floating objects, duplicated limbs, plastic gloss, waxy skin, synthetic collage artifacts, or AI watermarks. Return exactly one finished image composed for 3:4; no variants, process sheet, split panels, mockup frame, or contact sheet.

制作「社区屋顶降温节」活动海报，采用 3:4 画布，面向普通社区参与者。使用“屋顶色卡变成城市温度剖面”解释活动主题，真实接缝和受力痕迹优先于装饰效果。整体依照偏心竖构图组织，留白只用于强化核心隐喻。主字「社区屋顶降温节」先被读到，随后是「把一次观察留给下一位来者」和「旧水厂北厅／提前十分钟签到」，不可出现乱码。把导向箭头、手写纸条和材料样本作为主物证据；木刻线条与暖白棉纸保留真实纹理，雨蓝、墨黑、纸白与玫瑰红按主色、辅助色、强调色分配。用带遮光罩的顶灯揭示材料厚度，反射光只补暗部，阴影不可相互矛盾。最终图像仅含招贴本身，裁切不碰关键信息，并为「社区屋顶降温节」的活动信息留足空间；不借品牌、明星、IP、HUD、二维码或奢华展示获取注意，保持「社区屋顶降温节」的公共活动语气。
