## Prompt

```
Generate a high-key graphic poster based on any subject: The upper half of the image establishes a dense and orderly array of line-drawn group portraits or similar symbols. All elements are repeatedly arranged with thin black lines, simplified facial features, or geometric outlines, forming a rhythm similar to a wall of people; in this homogeneous repetition, set a clear thematic focus. The focus does not win by complex realism but is recognized at a glance through small-area theme-derived accent colors, slight contrast, local blank space, or morphological differences, creating a visual moment of "suddenly being seen among many similar individuals." Below, a large quiet information area is reserved. The main title uses heavy, compact, low-center-of-gravity black block characters. The typeface has a poster printing feel and strong weight. Auxiliary text forms a rational explanatory layer with small font sizes, neat line spacing, and clear alignment. Image density and text white space form an upper-lower contrast. Colors are extracted from the material, emotion, and semantics of the subject itself, without copying fixed color numbers: a large area of background serves as a bright and clean structural base color, occupying the main visual area; black or dark lines bear the order, text, and information skeleton; a small amount of high-saturation theme accent color falls only on key focal points or necessary details, with a restrained area but striking position. The overall style remains transparent, light, and clean with a high-key temperament, clear edges, uniform lines, and simple color levels, avoiding stacked shadows, dirty textures, and realistic impurities, so that the subject is quickly remembered through repetitive arrays, single-point differences, and steady text weight.

## 中文提示词

围绕任意主题对象生成一张高明度平面图形海报：画面上半部建立密集而有秩序的线描群像或同类符号阵列，所有元素以细黑线、简化五官或几何轮廓重复排列，形成近似人群墙面的节奏；在这片均质重复中设置一个清晰的主题焦点，焦点不靠复杂写实取胜，而通过小面积主题派生强调色、轻微反差、局部留空或形态差异被一眼识别，制造“在众多相似个体中突然被看见”的视觉瞬间。下方保留大块安静信息区，主体标题使用厚重、紧凑、低重心的黑色块面字，字形有海报印刷感和强烈重量，辅助文字以小字号、整齐行距和明确对齐形成理性说明层，图像密度与文字留白形成上下对照。色彩从主题自身的材质、情绪和语义中提取，不照搬固定色号：大面积背景作为明亮洁净的结构底色，占据主要视觉面积；黑色或深色线条承担秩序、文字和信息骨架；少量高饱和主题强调色只落在关键焦点或必要细节上，面积克制但位置醒目。整体保持清透、轻快、干净的高明度气质，边缘清晰、线条均匀、色阶简单，避免阴影堆叠、脏旧纹理和写实杂质，使主题通过重复阵列、单点差异和沉稳文字重量被迅速记住。
