霜染秋山几何叠山清爽国风海报

Generate a bright and clean activity visual around any theme object: the frame uses a large area of pure white space as an airy background, making geometric symbols derived from the theme the first subjects to be seen, using multiple flat triangles, angles, or peaked blocks staggered and interlaced with each other to form a sense of layer-by-layer progression like mountains; the main blocks occupy the center and edges of the frame, allowing some forms to be cropped by the frame, while other smaller forms hang at the top or bottom to form an echo, maintaining a strong diagonal reading path. The theme text uses an extra-large scale mixture of Chinese and English, Chinese strokes are thick, square, with a small amount of rounded corners or cuts, English uses wide and flat geometric sans-serif fonts, text can be cropped by edges or blocked by graphics, so that characters and graphics compete for space without being completely separated. Colors are derived according to the theme, but maintain three roles: a large area of high-brightness clean white background, the main subject uses medium-saturation, relatively stable natural colors or theme primary colors, text and thin lines use low-brightness warm gold, earth gold or warm support colors within the theme, with a very small amount of cold-colored thin diagonal lines as speed and direction hints; overall brightness is high, saturation is restrained, boundaries are clean, no dirty or old particles. Graphics are vector poster texture, block flat coating, outer edges have extremely thin strokes or same-color outlines, internal can add a small amount of wireframe triangles and slender diagonal lines, allowing slight movement in empty spaces. Information layout maintains a poster-style rhythm: top places small logos and date-style short messages, middle retains tiny explanatory text, corners can place small black and white identification-code-style blocks and action phrases, all small words are low-key, tight, clearly aligned, only as rhythm points. Avoid real depth of field, photographic texture, complex gradients and excessive decoration, focusing on retaining the refreshing festival poster temperament of large blocks of geometric symbols and giant text pressing, interlacing and cropping each other in white space.

围绕任意主题对象生成明亮洁净的活动视觉：画面以大片纯白留白作空气感底色，让主题派生的几何符号成为最先被看见的主体，使用多个扁平三角、折角或尖顶块面相互错位穿插，形成像山峦般的层层推进感；主要块面占据画面中部与边缘，允许部分形体被画面裁切，另一些较小形体悬在上方或底部形成呼应，保持强烈的对角阅读路径。主题文字采用超大尺度的中英文混排，中文笔画厚重、方正、带少量圆角或切口，英文使用宽扁的几何无衬线字形，文字可被边缘裁掉，也可被图形遮挡，使字与图互相抢占空间而不完全分离。色彩按主题派生，但保持三类角色：大面积高明度洁白背景，主体使用中等饱和、偏沉稳的自然色或主题主色，文字与细线使用低明度暖金、土金或主题中的温暖支撑色，另以极少量冷色细斜线作为速度和方向提示；整体明度高、饱和度克制、边界干净，不做脏旧颗粒。图形为矢量海报质感，块面平涂，外沿有极细描边或同色系轮廓线，内部可加入少量线框三角和细长斜线，让空白处也有轻微运动。信息排布保持海报式节奏：上方放小型标识与日期式短信息，中部保留细小说明文字，角落可放小型黑白识别码式方块和行动短句，所有小字低调、紧密、对齐清晰，只作为节奏点。避免真实景深、摄影质感、复杂渐变和过度装饰，重点保留大块几何符号与巨型文字在留白中相互压迫、穿插、裁切的清爽节庆海报气质。
