中文提示词
@Create image {argument name="city" default="CITY"} — 大写英文城市名称 {argument name="subject" default="一个作为最高点的地标建筑，一个稍低的主体结构，下方为中层建筑或地形带，底部为树木或水体组成的闭合块面"} — 重叠成一个轮廓，忽略真实地理位置，所有元素下方逐渐消融于留白纸面 {argument name="palette" default="主色 (深色) / 点缀色 (高饱和度) / 辅助色 1 / 辅助色 2 (柔和色)"} — 仅限四种颜色 {CAPTION} — 3 至 5 个单词的英文短句，随性，切忌解释性文字 --- [比例] 竖向 3:4 [主体] {SUBJECT} [风格] 优先体现水彩质感：湿画法产生的晕染，洗色干燥后形成的深色硬边，以及因含水量变化而在单次笔触中产生的密度差异。颜料在每个形状的下缘汇聚；干擦笔触产生裂纹，显露出冷压水彩纸的纹理。 先用粗毛笔勾勒主要轮廓 — 约 40 笔，不使用排线。 水彩渲染层与线条错位 1 至 3 毫米；颜色绝不与轮廓线重合。 覆盖率 60% — 未着色的纸面是画面中最亮的色调。 窗户由不均匀间隔的短促笔触构成，绝不单独绘制。 形态由平涂色块和线条构成，不使用明暗建模。 [色彩] 仅限四色：{PALETTE}。 底色为奶油色偏白纸张，每种颜色降低一个饱和度等级，以呈现复古印刷色调。 点缀色覆盖面积不超过画面的 8%。 [构图] 主体集中在下三分之二区域，左右留白；上三分之一为留白纸面，用于书写文字。 最高的尖塔可略微延伸至留白区域。 天空和地面保持留白。 [排版] 顶部："{CITY}" 使用超大号粗犷笔刷字体，全大写，跨度几乎覆盖整个宽度，字间距宽，笔触中带有干擦产生的白色纹理，笔画末端开裂。使用主色。 右下角："{CAPTION}" 小型手写体，使用点缀色。 标识为抽象的色块 — 不包含其他可读文字。 [负面提示词] 照片级真实感，3D，喷笔，渐变阴影，投影，反射，Logo，水印，边框，绘制的天空，乱码文字，均匀饱和的全覆盖，机械化的窗格，细字体，衬线或手写展示字体，比例 4:5。
原始提示词
@Create image {argument name="city" default="CITY"} — uppercase English city name {argument name="subject" default="one hero landmark as the highest point, one secondary structure a step lower, a mid-rise or terrain band beneath, a closing mass of trees or water at the bottom"} — overlapping into ONE silhouette, real geography ignored, everything below it dissolving into bare paper {argument name="palette" default="MAIN (dark) / ACCENT (saturated) / SUB1 / SUB2 (muted)"} — Four colors only {CAPTION} — 3–5 word English line, offhand, never explanatory --- [ASPECT RATIO] Vertical 3:4 [SUBJECT] {SUBJECT} [STYLE] Watercolor materiality first: wet-on-wet blooms, dark hard edges where a wash dried, density shifting within a single stroke as the water load changes. Pigment pools at the lower edge of each form; dry-brush passages split and let the cold-press tooth show through. A thick brush pen lays the main contours first — about 40 strokes, no hatching. Washes cross those lines 1–3 mm off register; color never doubles as the outline. Coverage 60 percent — the untouched paper is the brightest value in the image. Windows are short repeated strokes at uneven intervals, never drawn individually. Form comes from flat washes and line, never from modeling. [COLOR] Four only: {PALETTE}. Cream off-white paper ground, every color one step down in saturation for a vintage print tone. Accent covers 8 percent of the frame at most. [COMPOSITION] Subject mass in the lower two thirds with clear margins left and right; upper third is unpainted paper for the lettering. The tallest spire may pierce slightly into it. Sky and ground stay bare paper. [TYPOGRAPHY] Top: "{CITY}" in oversized heavy brush lettering, all caps, spanning nearly the full width, wide letter spacing, dry grain streaking white through the strokes, ends splitting. MAIN color. Bottom right: "{CAPTION}" small handwritten script, ACCENT color. Signage is abstract blocks of color — no other legible text. [NEGATIVE] photorealistic, 3D, airbrush, gradient shading, cast shadows, reflections, logos, watermarks, border frames, painted sky, gibberish lettering, evenly saturated full coverage, mechanical window grids, thin typography, serif or script display fonts, Aspect ratio 4:5.
