小雨中的蓝调

为「小雨中的蓝调」设计 1:1 原创招贴，活动规模克制且非商业。使用“萨克斯气流与细雨斜线逆向交叉”解释活动主题，真实接缝和受力痕迹优先于装饰效果。构图采用偏心竖构图，主物是第一视点，标题与活动小字沿随后动线展开，并为「小雨中的蓝调」的活动信息留足空间。可见文案只有「小雨中的蓝调」「用双手完成一次相遇」「桥下声场」「携带有线耳机」，按标题、副句、信息三级排版。只让分贝刻度、线缆弧线和吸音毡进入背景，并以蓝晒声谱叠加压凹波纹统一图像与文字，色彩不超过铁锈红、站台灰、米黄与孔雀蓝所列范围。照明设为接近地平线的晨光，高光与纸面漫反射分别可信，不做舞台泛光。四边给文字留出安全距离，只输出可印海报本体，服务于「小雨中的蓝调」的单一视觉命题；不出现墙面、手持展示、机器可读代码、名人或赛博界面。

Design an original 1:1 placard titled “Blues in Light Rain” for a restrained, noncommercial gathering. Use saxophone airflow crossing diagonal rain in the opposite direction to explain the event, prioritizing real seams and load traces over decoration. Use an asymmetric vertical composition; the hero is the first focal point, followed by title and event copy. Visible copy is limited to “Blues in Light Rain,” “Complete an encounter with both hands,” “the acoustic space beneath the bridge,” and “bring wired headphones,” arranged in three levels. Allow only decibel marks, cable arcs, and acoustic felt in the background. Unify image and type through a cyanotype sound spectrum over debossed wave ridges, remaining within rust red, platform gray, rice beige, and peacock blue. Set illumination to low morning light near the horizon, separating believable highlights from paper diffusion and avoiding theatrical bloom. Give copy safe distance from every edge and output the print itself. Include no wall, hand, machine-readable code, celebrity, or cyber interface. For the final rendering, give the metaphor a clear beginning, transition, and resting point: saxophone airflow crossing diagonal rain in the opposite direction. Use depth only around the hero; the remaining sheet should behave like disciplined editorial print. The final sheet should feel suitable for a local noticeboard, not a campaign billboard. 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 1:1; no variants, process sheet, split panels, mockup frame, or contact sheet.
