导读
本文是一份可直接落地的 AI 图像生成提示词手册,面向需要为开源项目创作品牌吉祥物的开发者与设计师。它以 OpenMed 仓库中 docs/brand/mascot-image-prompts.md 提供的完整提示词库为核心,结合 docs/brand/MASCOT_BRIEF.md 设计简报与品牌系统源码,讲解如何用 ChatGPT / GPT-image 逐条生成、比较、迭代四个吉祥物方向的图像。读完本文,你将掌握一套"复制即用"的英文提示词模板、配套衍生图(favicon / hero / 无字版)的生成方法,以及让生成结果始终贴合品牌调色板与法律边界的迭代技巧。
OpenMed 是一个 Apache-2.0 许可、本地优先(local-first)的临床 AI SDK,其吉祥物的核心任务是用一个友善形象传达"你的数据由我守护"(guardian of your data)的品牌承诺。下面这张波斯猫形象正是该文档重点推荐的 front-runner 方向——一只化身伊本·西那(Avicenna)的波斯白猫,守护着摊开的《医典》(Canon of Medicine)。
一、从设计简报理解吉祥物的灵魂:Guardian of your data
在动手复制提示词之前,先理解这些提示词为什么这样写。根据 docs/brand/MASCOT_BRIEF.md,OpenMed 的每一个吉祥物方向都是同一个主题的变体:
一个守护者,守护用户最敏感的数据,让处理始终贴近用户本地。
数据是珍贵的(treasure / flock / vault),吉祥物守护着它,快速而警觉。这个单一概念把吉祥物和 OpenMed 的核心价值精确绑定:隐私、本地优先、设备端、主权、可信。简报同时给出了严格的性格基调——保护、警觉、温暖、沉稳、干净现代;而绝不能是:攻击性、幼稚化、昏昏欲睡、混乱花哨、或者"千篇一律的 AI 金属机器人"。
情绪上的一句话概括是:"一切有我,你的数据在我这里很安全。"而 OpenMed 的一行式承诺则是"Local-first clinical AI on hardware you control."(本地优先的临床 AI,跑在你控制的硬件上)。
简报中定义的四个方向
| 方向 | 隐喻 | 气质 | 适合场景 |
|---|---|---|---|
| 守护龙 (Guardian Dragon) | 龙守护财宝,数据即珍宝 | 勇猛但仁慈、警觉、温暖 | 大尺寸 hero banner |
| 守护圣伯纳犬 (Guardian Saint Bernard) | 阿尔卑斯救援犬,颈桶变成急救包 | 忠诚、令人安心、温柔巨人 | 最广为人接受的暖色形象 |
| 狮鹫 (Griffin) | 神话中的财宝守护者,鹰眼 + 狮力 | 庄严、有力、古老守护者 | 独特而可拥有的形象 |
| 波斯猫 (Persian Cat) | 化身伊本·西那,医学经典的传承者 | 温暖、智慧、平静、学者气 | 项目维护者的个人首选 |
这四组提示词全部收录在 mascot-image-prompts.md 中,下面的章节会逐条给出可复制使用的完整原文。
二、精选方向:波斯猫(Avicenna 灵感)——完整提示词
文档明确指出Persian Cat(Avicenna-inspired)是个人 front-runner(首选方向)。它的文化隐喻非常完整:
- 传承:伊本·西那(Ibn Sina / Avicenna),伟大的波斯医学家,其《医典》(Canon of Medicine)作为世界标准医学教科书长达约 600 年 → 象征物 = 摊开的《医典》(一本打开的书)。
- 配色彩蛋:绿松石(fīrūza)是波斯国石,恰好近似 OpenMed 的青色(teal),因此波斯阿拉伯式花砖图案完全契合品牌调性。
直接复制以下提示词到 GPT-image,一次只生成一张(GPT-image 每条提示词只产出一张图):
Create a friendly mascot logo of a fluffy white Persian cat as the gentle guardian-physician of your private health data — inspired by Avicenna (Ibn Sina), the great Persian doctor who wrote "The Canon of Medicine." The plump, long-haired Persian cat sits upright with a warm, calm, kind expression, a flat round face, and big gentle eyes. It wears a small traditional Persian scholar's turban (in the style of Avicenna) and a slim collar with a small round tag showing a coral-red medical plus (+). In front of the cat lies a simple open book — a stylized "Canon of Medicine" — with a bold coral-red medical plus (+) on the page and a soft warm-yellow glow rising from it, like precious knowledge. A subtle Persian turquoise arabesque (tilework) pattern decorates the book's cover. Beneath the character, the wordmark "OpenMed" in a clean bold modern sans-serif — "Open" in dark ink and "Med" in teal. Spell it exactly "OpenMed". Style: modern flat vector mascot/logo illustration, bold clean dark outlines, simple rounded shapes, stylized shape-based fluffy fur (not individual strands), minimal flat shading, friendly proportions; the polished, ownable feel of a great open-source mascot. Color palette (stick to these): cream / off-white fur (#F7F4EC) with soft deep-teal accents on the ears and tail tip (#0D6E6E to #128787); a teal turban and collar; the medical plus and small accents in coral red (#C5453A); a Persian-turquoise (#128787) arabesque pattern; dark ink outlines (#0E1116); a soft warm-yellow glow (#F5E27A), used sparingly. Composition: a single character, centered, with generous empty margins, on a solid flat off-white (#F7F4EC) background — no extra scenery, uncluttered. Square 1:1. Avoid: realistic photographic fur; any real Red Cross emblem (use only the coral plus); national flags or politically charged emblems; gradients, 3D rendering, or photorealism; busy backgrounds; menacing looks; any text other than the word "OpenMed" (spelled correctly).这条提示词的结构值得拆解——它本身就是一份完整的品牌设计规格书,包含五个层次:角色设定(白色波斯猫、学者头巾、珊瑚红加号项圈)、象征物(摊开的《医典》+ 知识金辉 + 波斯花砖)、字标(OpenMed,Open 深墨 / Med 青色)、风格(现代扁平矢量、粗黑描边、无渐变)、规避清单(红十字徽记、国旗、3D、写实毛发、多余文字)。
配套提示词(锁定猫形象后生成)
1. 图标 / favicon——仅头部(小尺寸下的关键形态):
Create a simple app icon of the OpenMed Persian cat — JUST the head, ultra-simplified. A fluffy white Persian cat face wearing a small teal Persian turban, big friendly teal-green eyes, and a small coral-red medical plus (+) tag at the neck. Bold thick clean outlines, minimal detail, flat vector — must stay crystal-clear at 32x32 pixels. Cream (#F7F4EC) fur, deep-teal (#0D6E6E) turban, coral (#C5453A) cross, dark ink (#0E1116) outlines. Centered on solid flat off-white (#F7F4EC), generous margin, no text. Square 1:1.2. 无字标 hero 版(让 "OpenMed" 文字可以在代码 / 本地化中清晰排版):
The same OpenMed Persian-cat-with-open-Canon-of-Medicine mascot, but with NO text or wordmark — just the cat and the book. Keep the flat vector style and cream/teal/coral palette. Plain solid white background for easy cutout. Square 1:1.3. 可选 v2 清理版(修复常见瑕疵:双十字、光效来源、头巾尺寸):
Refine the OpenMed Persian cat: keep the coral cross on the open book as the main medical symbol and simplify the collar tag to plain teal (no second cross); make the warm-yellow glow clearly rise only from the book's pages, not from the cat's chest; make the teal turban a little larger and more clearly wrapped like a scholar's turban. Same flat vector style and palette, cream background, square 1:1.这条 v2 提示词的价值在于:它展示了一种迭代修补模式——AI 生成结果往往会在细节上犯错(双十字、光效位置、头巾比例),你不需要重新写整条提示词,只需针对具体瑕疵追加一段"Refine…"指令。
三、备选方向一:守护龙(Guardian Dragon)
龙是神话中最经典的"财宝守护者",在这里守护的是用户私密的医疗数据。提示词要求"可爱但自信",蜷曲环绕一个带珊瑚红医疗加号的金色发光宝库,神情平静警觉——"你的数据在我这里很安全":
Create a friendly mascot logo of a guardian dragon protecting a hoard of private health data. A small, cute-but-confident dragon is curled protectively around a rounded vault with a single bold coral-red medical plus (+) on its front; a soft warm-yellow glow rises from the vault like precious treasure. The dragon has large kind eyes, a soft rounded snout, small friendly horns, and half-folded wings. Its expression is calm and watchful — "your data is safe with me." Style: modern flat vector mascot/logo illustration, bold clean dark outlines, simple smooth shapes, minimal flat shading, rounded friendly proportions; the polished, ownable feel of a great open-source mascot. Color palette (stick to these): dragon body deep teal (#0D6E6E to #128787); cream / off-white belly and inner wings (#F7F4EC); medical plus and tiny accents in coral red (#C5453A); dark ink outlines (#0E1116); a soft warm-yellow glow (#F5E27A) used sparingly. Composition: a single character, centered, with generous empty margins, on a solid flat off-white (#F7F4EC) background — no scenery, no text, no letters. Square 1:1. Avoid: scary fangs, fire, or aggression; any real Red Cross emblem (use only the coral plus); gradients, 3D rendering, or photorealism; any text.注意这里与其他方向的关键差异:没有字标(no text, no letters),龙本身必须独立成立。同时规避项明确禁止"獠牙、火焰、攻击性"——守护者必须是友善的。
四、备选方向二:守护圣伯纳犬(Guardian Saint Bernard)
把阿尔卑斯救援犬重新想象为医疗数据守护者:颈上的经典救援小木桶在这里变成了急救包(medkit),标着单个珊瑚红医疗加号;一只前爪守护性地搭在小盾牌上。最特别的设计约束是——把圣伯纳犬标志性的棕色斑块改涂成深青色以保持品牌一致:
Create a friendly mascot logo of a guardian Saint Bernard — the classic Alpine rescue dog, reimagined as the gentle protector that keeps your private health data safe. A big, calm Saint Bernard sits upright on guard with a warm, reassuring expression: broad head, soft floppy ears, gentle soulful eyes, soft jowls, and a white blaze running up the muzzle. Around its neck, on a sturdy collar, hangs the iconic little rescue barrel (cask) — here it's a medkit, marked with a single bold coral-red medical plus (+). One front paw rests protectively on a small shield. Style: modern flat vector mascot/logo illustration, bold clean dark outlines, simple rounded shapes, stylized shape-based fur (not detailed strands), minimal flat shading, friendly "gentle giant" proportions; the polished, ownable feel of a great open-source mascot. Color palette (stick to these): cream / off-white base coat, chest, muzzle blaze and paws (#F7F4EC); the Saint Bernard's signature patches — over the back, the ears, and as a soft mask around the eyes — in deep teal (#0D6E6E to #128787) INSTEAD of the usual brown; the rescue barrel in warm cream with deep-teal bands; the medical plus on the barrel in coral red (#C5453A); dark ink outlines (#0E1116); a soft warm-yellow (#F5E27A) accent used sparingly. Composition: a single character, centered, with generous empty margins, on a solid flat off-white (#F7F4EC) background — no scenery, no text, no letters. Square 1:1. Avoid: bared teeth, drooling, sadness, or any menace (keep it gentle and friendly); realistic photographic fur; the usual brown coat (use teal patches); any real Red Cross emblem (use only the coral plus); gradients, 3D rendering, or photorealism; any text.INSTEAD of the usual brown这种写法正是提示词工程中"主动否定"的典型手法——AI 对圣伯纳犬的棕色先验极强,必须显式覆盖。
五、备选方向三:狮鹫(Griffin)
狮鹫(鹰头狮身)是神话中守卫财宝的贵族守护者,在这里被"柔化、圆润化":展开双翅呈保护姿态立于带珊瑚红加号的宝库之上,眼神锐利但和善。色调上青色羽毛 + 奶油色面部与狮身,黄色只用于喙和爪的高光:
Create a friendly mascot logo of a regal guardian griffin (eagle head, lion body, feathered wings) standing watch over private health data — an ancient, noble protector, but softened and approachable. The griffin is perched proudly with wings slightly spread in a protective, shielding stance over a small rounded vault bearing a single bold coral-red medical plus (+). Sharp but kind eyes; alert and dignified, with a rounded, friendly silhouette rather than anything sharp or aggressive. Style: modern flat vector mascot/logo illustration, bold clean dark outlines, simplified rounded heraldic shapes, minimal flat shading, elegant yet warm; the polished, ownable feel of a great open-source mascot. Color palette (stick to these): teal plumage and wings (#0D6E6E to #128787); cream / off-white face, chest feathers, and lion fur (#F7F4EC); medical plus in coral red (#C5453A); a soft warm-yellow (#F5E27A) beak and talon highlight, used sparingly; dark ink outlines (#0E1116). Composition: a single character, centered, with generous empty margins, on a solid flat off-white (#F7F4EC) background — no scenery, no text, no letters. Square 1:1. Avoid: menacing or corporate-aggressive looks; any real Red Cross emblem (coral plus only); gradients, 3D rendering, or photorealism; any text.六、提示词系统解剖:调色板、风格与构图规范
四组提示词共享同一套"品牌约束引擎",这在源码层面也能找到对应证据。提示词中反复出现的色值如下:
| 角色 | 色值 | 用途 |
|---|---|---|
| 奶油 / 米白 | #F7F4EC | 毛发、肚皮、面部、背景底色 |
| 深青色 | #0D6E6E→#128787 | 龙鳞、猫的头巾项圈、犬的斑块 |
| 珊瑚红 | #C5453A | 医疗加号与关键点缀 |
| 墨色描边 | #0E1116 | 轮廓线 |
| 暖黄 | #F5E27A | 知识 / 财宝光效,克制使用 |
风格基调(每个方向都要求):现代扁平矢量吉祥物插画、粗黑干净描边、圆润简洁形状、基于形状的毛感(而非一根根毛发)、最少扁平阴影、友好比例——追求"顶级开源吉祥物的精致与可拥有感"。构图一律是:单一角色、居中、留白充足、纯色米白背景、方形 1:1。
需要说明的版本背景:这套 teal/cream/coral 调色板来自 mascot-image-prompts.md 生成提示词时所依据的早期品牌阶段。根据 MASCOT_BRIEF.md 的状态说明,2026 年 7 月的设计系统更迭后,新品牌的主色引擎已改为以信号红#B0413E为唯一基础色、配合冷色浅底与蓝黑深色表面(见 system/tokens/colors.css 中的--om-accent-base: #B0413E与 system/claims.yml 的约束)。MASCOT_BRIEF 明确指示保留已入库的猫 crest 原样,不要对历史栅格重新着色。因此,如果你要在今天的 OpenMed 品牌语境中重新生成新图,应把提示词里的 teal/coral 视作历史探索调色板,并以 docs/brand/README.md 与system/tokens.json作为当前生产环境的唯一事实来源。文档本身也提示:精确 hex 不保证被 AI 严格遵守,同时写出 hex 和颜色词汇(如 deep teal, cream, coral)可以显著提高命中率。
七、使用技巧:单张生成、迭代与救场指令
mascot-image-prompts.md 提供了经过实战检验的工作流建议:
- 一条提示词 → 一张图。分别运行、对比,再对最喜欢的方案进行迭代。
- 如果画面漂移成 3D 或跑色,回复:"Flatter, more limited palette — just deep teal, cream, and coral. Bold flat vector, no gradients, no 3D."
- 波斯猫方向要盯住字标。GPT-image 经常拼错文字。如果 "OpenMed" 出错,重新生成,或者只生成干净的猫、把字标交给代码排版。同时保持画面简洁:"Simplify — just the cat, the open book, and the OpenMed word."
- 如果圣伯纳犬被生成成棕色,回复:"Recolor the patches to deep teal (#0D6E6E), keep the rest cream — no brown."
- 生成小尺寸 app 图标 / favicon(选定形象后):"Now show just the head/face as a simple app icon that stays clear at small sizes — same colors, flat vector."
- 生成 README hero banner:"Place this character on the left and the word 'OpenMed' in a bold modern sans-serif on the right ('Med' in teal), wide 16:9 banner, cream background."
- 生成干净可抠图版本:"Same mascot on a plain solid white background"→ 方便后期移除背景。
- Hex 不保证精确,但"hex + 颜色词汇"双写能拉近距离;可以请求"3 variations of this pose"以获得更多选项。
这套技巧对应的是文档强调的单张生成、对比、迭代的核心工作流:不追求一次到位,而是把每一次输出当作下一轮提示词的输入。
八、法律与品牌安全红线
这是提示词中最重要的"隐形约束",在 MASCOT_BRIEF.md 中有专门一节警示:
- 严禁使用红底白十字的官方红十字徽记。红十字 / 红新月徽记受《日内瓦公约》及各国商标法保护。必须使用我们的珊瑚红或青色加号(coral or teal "plus"),或明确风格化的十字——绝不能在白底上画正式的红十字。
- 角色必须原创。不得是现有品牌吉祥物、游戏角色或图库插画的明显重绘。
此外还有一组通用"Don'ts"(不可为清单):不要注射器、针头、血液或写实解剖;不要獠牙、武器或威胁性姿态(我们是友善守护者);不要千篇一律的金属/镀铬"AI 机器人"套路;不要重写实或渐变(无法印刷和缩放);不要跑出调色板。这些约束已经在每条提示词的Avoid:段落中逐条落实。
九、从提示词到品牌资产:猫 crest 在 OpenMed 品牌系统中的实际定位
提示词生成只是第一步。如果你好奇最终资产如何被品牌系统治理,可以参考 docs/brand/system/iconography.md。它明确记录:OpenMed 拥有两套互补的身份体系,且都不是通用头像——网站与文档 chrome、favicon 使用Open Cross(docs/brand/assets/open-cross.svg)+ 小写字标作为产品身份;而猫 crest 是社区角色,仅用于已批准的 README / 社交合成图,以及 Hugging Face 组织头像(使用 docs/brand/social/exports/avatar-cat-2x.png 1024² 导出物)。猫 crest 的使用规则包括:保留docs/brand/assets/cat-crest.png的 502×462 原始画布与 alpha 通道、固定调色板无反色/单色变体、禁止用于产品 chrome / favicon / X 头像 / LinkedIn 公司格,且非社交场景渲染最短边不小于 96 CSS 像素。这与 MASCOT_BRIEF 的"superseded for new brand work"状态一致——本文的提示词文档是探索阶段的历史记录,而当前品牌的权威事实来源是 docs/brand/README.md 及其system/子目录。
结语
这套提示词库的完整价值在于:它把"品牌气质"翻译成了可复制的结构化英文指令——角色故事、象征物、五角色调色板、扁平矢量风格、方形构图、规避清单,五个层次缺一不可。无论你最终选择波斯猫、守护龙、圣伯纳犬还是狮鹫,只要保持"守护者 + 珊瑚红加号 + 扁平矢量 + 克制调色板"的核心约束,并配合"单张生成、逐条比较、Refine 修补"的迭代节奏,就能稳定产出与 OpenMed 品牌同频的原创吉祥物资产。生成之后,请务必对照 iconography.md 的治理规则确认每个产物的适用场景,让创意产出落在品牌边界之内。
