步骤 3：改变蒸汽的颜色

{"scene":"专业摄影棚产品拍摄场景，搭配抛光水泥台面","subjects":[{"description":"极简风陶瓷咖啡杯，杯中热咖啡升腾着鲜艳的红色蒸汽","pose":"放置于台面静止不动","position":"在抛光水泥台面的前景中央位置","color_palette":["哑光黑陶瓷材质","鲜艳红色蒸汽"]},{"description":"与黑色咖啡杯设计一致的极简风陶瓷咖啡杯","pose":"放置于台面静止不动","position":"在抛光水泥台面上黑色咖啡杯的右侧","color_palette":["哑光黄陶瓷材质"]}],"style":"达到商业级品质的超写实产品摄影风格","color_palette":["哑光黑","哑光黄","鲜艳红","水泥灰","柔和白色高光"],"lighting":"采用三点柔光箱布光方案，形成柔和且弥散的高光效果，无生硬阴影","mood":"整洁、专业、极简的氛围","background":"带有摄影棚背景板的抛光水泥台面","composition":"遵循三分构图法则","camera":{"angle":"高角度拍摄","distance":"中景镜头","focus":"清晰对焦于咖啡升起的蒸汽及画面内的两个咖啡杯","lens-mm":85,"f-number":"f/5.6","ISO":200}}{"scene":"Professional studio product photography setting with polished concrete countertop","subjects":[{"description":"Minimalist ceramic coffee mug with vivid red steam curling up from the hot coffee inside","pose":"Stationary on the countertop","position":"Center foreground on the polished concrete countertop","color_palette":["matte black ceramic","vivid red steam"]},{"description":"Minimalist ceramic coffee mug that matches the design of the black one","pose":"Stationary on the countertop","position":"Right side of the black mug on the polished concrete countertop","color_palette":["matte yellow ceramic"]}],"style":"Ultra-realistic product photography with commercial-grade quality","color_palette":["matte black","matte yellow","vivid red","concrete gray","soft white highlights"],"lighting":"Three-point softbox lighting setup producing soft, diffused highlights without harsh shadows","mood":"Clean, professional, minimalist atmosphere","background":"Polished concrete countertop with studio backdrop","composition":"Adheres to the rule of thirds","camera":{"angle":"High-angle shot","distance":"Medium shot","focus":"Sharp focus on the steam rising from the coffee and both mugs in the frame","lens-mm":85,"f-number":"f/5.6","ISO":200}}

您可以直接在提示符中包含 JSON 数据，也可以将其转换为自然语言。FLUX.2 支持这两种格式。

十六进制颜色代码提示

FLUX.2 支持使用十六进制代码进行精确的颜色匹配。对于品牌一致性和设计工作至关重要。

基本语法

使用“color”或“hex”等关键字，后跟代码，表示十六进制颜色：

The vase has color #02eb3cThe background is hex #1a1a2e花瓶的颜色是： #02eb3c背景的颜色是： #1a1a2e渐变色

通过指定起始颜色和结束颜色应用渐变：

提示：“A vase on a table in living room, the color of the vase is a gradient, starting with color #02eb3c and finishing with color #edfa3c. The flowers inside the vase have the color #ff0088”“客厅桌子上放着一个花瓶，花瓶的颜色是渐变色，从#02eb3c开始，到#edfa3c结束。花瓶里的花是#ff0088。”

JSON 提示中的颜色

将十六进制颜色与结构化提示相结合，实现最大程度的控制：

{"scene":"Makeup flat lay on marble surface","subjects":[{"description":"eyeshadow palette","colors":["#E91E63","#9C27B0","#673AB7","#3F51B5"]}],"style":"beauty product photography","lighting":"soft diffused overhead lighting"}{"scene":"大理石表面上的美妆平铺展示","subjects":[{"description":"眼影盘","colors":["#E91E63","#9C27B0","#673AB7","#3F51B5"]}],"style":"美妆产品摄影","lighting":"柔和的漫射顶光"}

十六进制代码与特定对象明确关联时效果最佳。诸如“在某处使用#FF0000”之类的模糊描述可能会导致结果不一致。

信息图表和数据可视化

FLUX.2 能生成排版清晰、布局结构合理的图表。

信息图表模{"type":"infographic","title":"Your Main Title","subtitle":"Supporting context","sections":[{"heading":"Section 1","content":"Key information","visual":"icon or chart type"}],"color_scheme":["#primary","#secondary","#accent"],"style":"modern, clean, corporate"}{"type":"信息图","title":"主标题","subtitle":"辅助说明","sections":[{"heading":"第一部分","content":"关键信息","visual":"图标或图表类型"}],"color_scheme":["#主色","#辅助色","#强调色"],"style":"现代、简洁、商务"}

提示示例：

“Create a vertical infographic about coffee consumption worldwide. Title: ‘Global Coffee Culture’. Include 3 sections with statistics, use icons for each country, color scheme #4A2C2A (brown) and #F5E6D3 (cream). Modern minimalist style with clean typography.”“制作一张关于全球咖啡消费的竖版信息图。标题：‘全球咖啡文化’。包含三个部分，分别展示统计数据，每个国家使用图标，配色方案为#4A2C2A（棕色）和#F5E6D3（米色）。采用现代简约风格，字体简洁。”

排版与设计

FLUX.2 擅长生成简洁的排版、产品营销材料和杂志版面。

产品广告： “Samsung Galaxy S25 Ultra product advertisement, ‘Ultra-strong titanium’ headline, ‘Shielded in a strong titanium frame, your Galaxy S25 Ultra always stays protected’ subtext, close-up of phone edge showing titanium frame, dark gradient background, clean minimalist tech aesthetic, professional product photography”“三星 Galaxy S25 Ultra 产品广告，标题为‘超强钛金属’，副标题为‘坚固的钛金属边框，让您的 Galaxy S25 Ultra 始终受到保护’，手机边缘特写，展示钛金属边框，深色渐变背景，简洁的极简科技美学，专业产品摄影”

杂志封面：“Women’s Health magazine cover, April 2025 issue, ‘Spring forward’ headline, woman in green outfit sitting on orange blocks, white sneakers, ‘Covid: five years on’ feature text, ‘15 skincare habits’ callout, professional editorial photography, magazine layout with multiple text elements”“《女性健康》杂志封面，2025年4月刊，标题为‘春回大地’，一位身穿绿色套装的女士坐在橙色方块上，脚穿白色运动鞋，专题文章为‘新冠疫情：五年后’，宣传语为‘15个护肤习惯’，专业编辑摄影，杂志版面包含多个文本元素”

多语言提示

FLUX.2 拥有出色的多语言理解能力。您可以使用母语进行提示，获得更具文化真实性的结果。

French: “Un marché alimentaire dans la campagne normande, des marchands vendent divers légumes, fruits. Lever de soleil, temps un peu brumeux”

Thai: “ตลาดอาหารเช้าในชนบทใกล้กรุงเทพฯ พ่อค้าแม่ค้ากำลังขายผักและผลไม้นานาชนิด บรรยากาศยามพระอาทิตย์ขึ้น มีหมอกจาง ๆ ปกคลุม สงบและอบอุ่น”

Korean: “서울 도심의 옥상 정원, 저녁 노을이 지는 하늘 아래에서 사람들이 작은 등불을 켜고 있다. 화려한 네온사인이 멀리 반짝이고, 정원에는 다양한 꽃들이 피어 있다. 분위기는 따뜻하고 낭만적이다

中文：“在诺曼底乡村的一个食品市场，商贩们正在售卖各种蔬菜和水果。日出时分，天气有些雾蒙蒙的。”

使用你所创作内容的母语进行提示，通常会产生更具文化真实性的结果——当地的市场、建筑和氛围都能更准确地呈现出来。

漫画和连环画

创作风格统一、人物形象连贯的漫画分镜。关键在于细致刻画人物，在所有分镜中保持人物形象的一致性。

Master FLUX.2 prompting with structured JSON, hex colors, and multi-reference techniques

FLUX.2delivers exceptional prompt following and supports advanced techniques like structured JSON prompting, precise hex color control, and multi-reference image editing. This guide covers everything you need to create stunning results.

No negative prompts:FLUX.2 does not support negative prompts. Focus on describing what you want, not what you don’t want.

JSON Structured Prompting

FLUX.2 excels at interpreting structured JSON prompts, giving you precise control over every aspect of your image. This is particularly powerful for production workflows and automation.

The Base Schema{"scene":"overall scene description","subjects":[{"description":"detailed subject description","position":"where in frame","action":"what they're doing"}],"style":"artistic style","color_palette":["#hex1","#hex2","#hex3"],"lighting":"lighting description","mood":"emotional tone","background":"background details","composition":"framing and layout","camera":{"angle":"camera angle","lens":"lens type","depth_of_field":"focus behavior"}}Building a Prompt Step by Step

Let’s build a product shot incrementally to see how each element contributes.

Step 1: Generating a coffee mug

{"scene":"Professional studio product photography setup with polished concrete surface","subjects":[{"description":"Minimalist ceramic coffee mug with steam rising from hot coffee inside","pose":"Stationary on surface","position":"Center foreground on polished concrete surface","color_palette":["matte black ceramic"]}],"style":"Ultra-realistic product photography with commercial quality","color_palette":["matte black","concrete gray","soft white highlights"],"lighting":"Three-point softbox setup creating soft, diffused highlights with no harsh shadows","mood":"Clean, professional, minimalist","background":"Polished concrete surface with studio backdrop","composition":"rule of thirds","camera":{"angle":"high angle","distance":"medium shot","focus":"Sharp focus on steam rising from coffee and mug details","lens-mm":85,"f-number":"f/5.6","ISO":200}}

Step 2: Adding a second mug in a different color

{"scene":"Professional studio product photography setup with polished concrete surface","subjects":[{"description":"Minimalist ceramic coffee mug with steam rising from hot coffee inside","pose":"Stationary on surface","position":"Center foreground on polished concrete surface","color_palette":["matte black ceramic"]},{"description":"Minimalist ceramic coffee mug, matching design to the black mug","pose":"Stationary on surface","position":"Right side of the black mug on polished concrete surface","color_palette":["matte yellow ceramic"]}],"style":"Ultra-realistic product photography with commercial quality","color_palette":["matte black","matte yellow","concrete gray","soft white highlights"],"lighting":"Three-point softbox setup creating soft, diffused highlights with no harsh shadows","mood":"Clean, professional, minimalist","background":"Polished concrete surface with studio backdrop","composition":"rule of thirds","camera":{"angle":"high angle","distance":"medium shot","focus":"Sharp focus on steam rising from coffee and both mugs in frame","lens-mm":85,"f-number":"f/5.6","ISO":200}}

Step 3: Change the color of the steam

{"场景":"专业影棚产品摄影布置，搭配抛光水泥表面","拍摄主体":[{"描述":"极简风格陶瓷咖啡杯，杯中热咖啡升腾着亮红色蒸汽","姿态":"静置在表面上","位置":"抛光水泥表面的前景中央","色彩搭配":["哑光黑色陶瓷","亮红色蒸汽"]},{"描述":"极简风格陶瓷咖啡杯，设计与黑色杯子相匹配","姿态":"静置在表面上","位置":"抛光水泥表面上黑色杯子的右侧","色彩搭配":["哑光黄色陶瓷"]}],"风格":"超写实商业品质产品摄影","整体色彩":["哑光黑","哑光黄","亮红","水泥灰","柔和白色高光"],"布光":"三点式柔光箱布置，营造柔和漫射高光，无生硬阴影","氛围":"干净、专业、极简","背景":"带影棚背景板的抛光水泥表面","构图":"三分法","相机参数":{"角度":"高角度","景别":"中景","对焦":"清晰对焦于升腾的咖啡蒸汽及画面内的两个杯子","镜头焦距-mm":85,"光圈值":"f/5.6","感光度":200}}

You can include the JSON directly in your prompt, or flatten it into natural language. FLUX.2 understands both formats.

HEX Color Code Prompting

FLUX.2 supports precise color matching using hex codes. This is essential for brand consistency and design work.

Basic Syntax

Signal hex colors with keywords like “color” or “hex” followed by the code:

"vase_color":"#02eb3c","background_color":"#1a1a2e"Gradient Colors

Apply gradients by specifying start and end colors:

Prompt: “A vase on a table in living room, the color of the vase is a gradient, starting with color #02eb3c and finishing with color #edfa3c. The flowers inside the vase have the color #ff0088”

Color in JSON Prompts

Combine hex colors with structured prompts for maximum control:

{"scene":"Makeup flat lay on marble surface","subjects":[{"description":"eyeshadow palette","colors":["#E91E63","#9C27B0","#673AB7","#3F51B5"]}],"style":"beauty product photography","lighting":"soft diffused overhead lighting"}

Hex codes work best when clearly associated with specific objects. Vague references like “use #FF0000 somewhere” may produce inconsistent results.

Infographics and Data Visualization

FLUX.2 can generate infographics with clean typography and structured layouts.

Infographic Template{"type":"infographic","title":"Your Main Title","subtitle":"Supporting context","sections":[{"heading":"Section 1","content":"Key information","visual":"icon or chart type"}],"color_scheme":["#primary","#secondary","#accent"],"style":"modern, clean, corporate"}

Example Prompt:

“Create a vertical infographic about coffee consumption worldwide. Title: ‘Global Coffee Culture’. Include 3 sections with statistics, use icons for each country, color scheme #4A2C2A (brown) and #F5E6D3 (cream). Modern minimalist style with clean typography.”

Typography and Design

FLUX.2 excels at generating clean typography, product marketing materials, and magazine layouts.

Product Ad: “Samsung Galaxy S25 Ultra product advertisement, ‘Ultra-strong titanium’ headline, ‘Shielded in a strong titanium frame, your Galaxy S25 Ultra always stays protected’ subtext, close-up of phone edge showing titanium frame, dark gradient background, clean minimalist tech aesthetic, professional product photography”

Magazine Cover: “Women’s Health magazine cover, April 2025 issue, ‘Spring forward’ headline, woman in green outfit sitting on orange blocks, white sneakers, ‘Covid: five years on’ feature text, ‘15 skincare habits’ callout, professional editorial photography, magazine layout with multiple text elements”

Multi-Language Prompting

FLUX.2 has excellent multi-language understanding. You can prompt in your native language for more culturally authentic results.

French: “Un marché alimentaire dans la campagne normande, des marchands vendent divers légumes, fruits. Lever de soleil, temps un peu brumeux”

Thai: “ตลาดอาหารเช้าในชนบทใกล้กรุงเทพฯ พ่อค้าแม่ค้ากำลังขายผักและผลไม้นานาชนิด บรรยากาศยามพระอาทิตย์ขึ้น มีหมอกจาง ๆ ปกคลุม สงบและอบอุ่น”

Korean: “서울 도심의 옥상 정원, 저녁 노을이 지는 하늘 아래에서 사람들이 작은 등불을 켜고 있다. 화려한 네온사인이 멀리 반짝이고, 정원에는 다양한 꽃들이 피어 있다. 분위기는 따뜻하고 낭만적이다”

Prompting in the native language of the content you’re creating often produces more culturally authentic results—local markets, architecture, and atmosphere are rendered with greater accuracy.

Comic Strips and Sequential Art

Create consistent comic panels with character continuity. The key is to define your character in detail and maintain that description across panels.

The Diffusion Man Story

Generate each panel separately while keeping character descriptions consistent:

Panel 1 Prompt: The Crisis

Prompt:“A spiritual architectural photograph captured on expired Kodak Ektachrome 64 slide film cross-processed from 1987 with a 35mm spherical lens at f/5.6, featuring model standing before small forest chapel in clearing. The model wears the outfit, positioned on stone steps leading to wooden chapel, red creating stark contrast against weathered brown timber. Background shows traditional Schwarzwald chapel – dark wood construction with small bell tower, carved wooden door, religious paintings under eaves, surrounding clearing with wild flowers, tall firs creating natural cathedral, small cemetery with wooden crosses. Dappled forest light at 1/125. Cross-processed Ektachrome showing extreme color shifts – cyan-magenta split, warm wood tones pushed to orange-brown, oversaturated red, crushed black shadows, blown highlights, heavy grain creating mysterious atmosphere. Composition emphasizes sacred spaces and pilgrimage. Thomas Struth church interiors, Candida Höfer architectural documentation, religious tourism meets fashion editorial, spiritual Schwarzwald mysticism.”

最佳实践摘要控制结构：当需要对多个元素进行精准控制时，使用JSON结构化提示词。从简单开始，根据需求逐步增加复杂度。颜色需明确：始终将十六进制代码与特定对象关联。“汽车是#FF0000”比“在图像中使用红色#FF0000”效果更好。描述需求内容：FLUX.2没有负面提示词。不要说“不要模糊”，而要说“全程清晰对焦”；不要说“不要有人”，而要描述“空场景”。参考相机与风格：追求照片真实感时，明确指定相机型号、镜头和胶卷类型。“使用富士X-T5拍摄，35mm f/1.4镜头”比“专业照片”能产生更真实的效果。使用母语：用最能描述所需文化语境的语言撰写提示词。比如巴黎场景用法语，动漫风格用日语。谨慎叠加多参考：使用多张输入图像时，清晰描述每张图的作用：主体来自图1，风格来自图2，背景来自图3。快速参考技巧类型 使用场景 关键语法JSON提示词 复杂场景、自动化 {"scene": "...", "style": "..."}十六进制颜色 品牌工作、精准匹配 color #FF5733 或 hex #FF5733相机参考 照片真实感 shot on [camera], [lens], [settings]风格年代 特定时期外观 80s vintage、2000s digicam多参考 合成图像 [pro]: 8, [flex]: 10, [dev]: ~6
