极简典礼感信息海报设计框架

Construct a minimalist ceremonial information poster around any theme. At first glance, it must be a precise centering of the main title and three theme symbols within a large area of warm white space, creating a solemn counterpoint: the theme provides core names, participants, or keywords, transformed into a large thin-stroke title at the top, a set of recognizable abstract symbols in the center, and solid color blocks on both sides; semantics change but the order remains constant. The image retains a high proportion of white space, a vertical central axis, top and bottom partitioning, and a sense of pause from thin black horizontal lines; all elements are restrainedly arranged like an exhibition catalog or an international organization yearbook. The main text uses high-contrast thin serifs or equivalent glyph structures, with open counters, thin strokes, sharp terminals, and spacious rhythm, maintaining a slender skeleton, wide letter spacing, clear recognition, and calm breathing when replaced with any writing system, rather than copying a specific Latin typeface. Colors are extracted from the theme into two high-purity representative colors as hard-edged blocks; the middle symbol uses only black lines and a few solid geometries; the background is a slightly paper-textured warm white, avoiding gradients, shadows, and decorative textures. The bottom places the subtitle and small explanatory text with a lower center of gravity, and the footer's three-point miniature information presses against the edges, forming a contrast where the grand theme is tamed by museum-style white space; failure symptoms are elements becoming full, colors becoming busy, fonts becoming thick, icons becoming realistic, or the poster losing its cool ceremonial order.

Set the theme as 'City Public Library Open Day' for the main poster of a public cultural institution event: use indigo and cinnabar red as the two high-purity block colors, abstractly represent open book pages and door arches with black lines in the center, and the symbol group falls steadily from below the title along the vertical central axis; the main title is placed in the center of the upper half, with the subtitle and date forming a sparse two-level information hierarchy below, retaining a large area of warm white space and thin black horizontal line pauses; the aspect ratio is vertical 3:4.

围绕任意主题内容构成极简典礼感信息海报，第一眼必须是大片温白空场中被精确居中的主标题与三枚主题符号发生庄重对位：主题提供核心名称、参与者或关键词，转化为上方大号细笔画标题、中央一组可识别的抽象标志和两侧纯色方块，语义可变但秩序不变。画面保留高比例留白、纵向中轴、上下分区和细黑横线的停顿感，所有元素像展览目录或国际机构年鉴一样被克制排布；主文字采用高反差细衬线或等效字形构造，字腔开阔、笔画纤细、端点尖净、节奏疏朗，换成任何文字系统时都保持修长骨架、宽松字距、清晰识别和冷静呼吸，而不是复制某种特定拉丁字体。色彩由主题抽取两枚高纯度代表色做硬边方块，中间标志只用黑线与少量实心几何，背景为轻微纸感温白，避免渐变、阴影和装饰纹理。底部以更低重心放置副标题与小号说明文字，页脚三点式微型信息压住边缘，形成宏大主题被博物馆式留白驯服的反差；失败症状是元素变满、颜色变花、字体变厚、图标写实或海报失去冷峻仪式秩序。

将主题设为“城市公共图书馆开放日”，用于公共文化机构活动主海报：以靛蓝与朱砂红作为两枚高纯度方块色，中央用黑线抽象出展开的书页与门拱，符号组沿纵向中轴从标题下方稳稳落下；主标题置于上半区正中，副标题与日期在下方形成稀疏的两级信息层级，保留大面积温白留白与细黑横线停顿；画幅为竖版 3:4。
