}

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 #02eb3c 
The 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。

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.”“这是一张摄于1987年的柯达Ektachrome 64幻灯片胶片照片，采用35mm球面镜头，光圈f/5.6，经交叉冲洗处理。照片中，模特站在林间空地上的一座小型森林教堂前。模特身着红色服装，站在通往木质教堂的石阶上，红色服装与风化的棕色木材形成鲜明对比。背景展现了传统的黑森林教堂——深色木结构，带有小钟楼、雕花木门、屋檐下的宗教绘画、周围开满野花的空地、高耸的冷杉构成天然的教堂，以及带有木制十字架的小型墓地。照片采用1/125秒的快门速度，拍摄时森林光线斑驳。交叉冲洗的Ektachrome胶片呈现出极端的色彩偏移——青色和品红色分离，温暖的木色调被推至橙棕色，红色过饱和，黑色阴影被压暗，高光过曝，厚重的颗粒感营造出神秘的氛围。构图强调了神圣的空间和朝圣的意义。托马斯·斯特鲁斯教堂内部，坎迪达·霍弗建筑文献，宗教旅游融合时尚杂志的风格，以及黑森林的神秘主义精神。”

• 颜色要具体明确：始终将十六进制代码与特定对象关联起来。“这辆车的代码是#FF0000”比“在图像中使用红色#FF0000”效果更好。
• 描述你想要什么：FLUX.2 没有否定提示。例如，不要说“没有模糊”，要说“始终清晰对焦”。不要说“没有人”，要描述“空旷的场景”。
• 参考相机和风格：为获得逼真的照片效果，请具体说明相机型号、镜头和胶片类型。“使用富士X-T5相机，35mm f/1.4镜头拍摄”比“专业照片”更能呈现真实效果。
• 使用母语：请用最能描述您所需文化背景的语言进行描述。例如，巴黎场景请用法语，动漫风格请用日语。
• 多层多重参考仔细：当使用多个输入图像时，请清楚地描述每个图像的作用：图像 1 代表主体，图像 2 代表风格，图像 3 代表背景。

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

{
    "scene": "Professional studio product photography setup with polished concrete surface",
    "subjects": [
        {
            "description": "Minimalist ceramic coffee mug with bright red steam rising from hot coffee inside",
            "pose": "Stationary on surface",
            "position": "Center foreground on polished concrete surface",
            "color_palette": ["matte black ceramic", "bright red steam"]
        },
        {
            "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", "bright red", "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
    }
}

    "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

“Style: Classic superhero comic Character: Worried scientist frantically typing on glowing holographic keyboard, face illuminated by blue light showing deep concern Setting: Massive computer server room with sparking circuits and red warning lights flashing on monitors Text: ‘The AI models are corrupting! We need Diffusion Man!’ Mood: Tense, urgent + dramatic blue and red tones”

Panel 2 Prompt: The Transformation

“Style: Classic superhero comic with dynamic action lines and electric energy effects Character: Diffusion Man/Mild-mannered programmer (30 years old, brown skin tone, short natural fade haircut with black hair, black-framed glasses, light blue button-up shirt, athletic build, strong jawline) body begins to glow with swirling gradients of deep purple, electric blue, and hot pink energy, mathematical equations and neural network patterns flowing around him in glowing lines Setting: Small office with computer monitors displaying code and error messages Text: ‘When noise becomes signal, I am… DIFFUSION MAN!’ Mood: Powerful, transformative + dramatic backlighting and energy radiating outward in waves”

Panel 3 Prompt: The Battle

“Style: Classic superhero comic with explosive action and dynamic composition Character: Diffusion Man (athletic 30-year-old with brown skin tone and short natural fade haircut with black hair, wearing sleek bodysuit with gradient patterns from deep purple to electric blue to hot pink, glowing neural network emblem on chest with interconnected nodes, short gradient cape, purple half-mask showing strong jawline and confident expression) extends both hands forward in powerful stance, shooting beams of structured noise and latent space energy at corrupted digital monsters made of glitching pixels and broken code Setting: Digital cyberspace environment with floating data cubes and cascading binary code Text: ‘Time to DENOISE this chaos!’ Mood: Intense, action-packed + bright energy flashes and electric effects”

Panel 4 Prompt: Victory

“Style: Classic superhero comic with warm, triumphant colors and clean composition Character: Diffusion Man (athletic 30-year-old with brown skin tone and short natural fade haircut with black hair, wearing sleek gradient bodysuit from deep purple to electric blue to hot pink, glowing neural network emblem on chest, short gradient cape flowing behind him, purple half-mask, strong jawline, confident heroic smile) stands heroically giving thumbs up gesture to grateful scientist beside him, her computer screens now showing stable green indicators and success messages Setting: Calm server room with soft blue ambient lighting and orderly data streams flowing smoothly in organized patterns Text: ‘You saved us, Diffusion Man! The models are generating perfectly again!’ Mood: Victorious, hopeful + golden sunset-like tones streaming through windows”

Character Consistency: Notice how Diffusion Man’s description stays detailed and consistent across panels—brown skin tone, short natural fade haircut, gradient bodysuit from purple to blue to pink, neural network emblem, purple half-mask. Repeat these details in every panel prompt.

Photorealistic Styles

FLUX.2 excels at photorealistic generation. Reference specific eras and techniques for distinctive looks.

Style Reference Guide

• Modern Photorealism: “Soaking wet tiger cub taking shelter under a banana leaf in the rainy jungle, close up photo”
• 2000s Digicam: “Sloth out drinking in Bangkok at night in a street full of party folks, 2000s digicam style, people in the background fading”
• 80s Vintage: “A group of baby penguins in a trampoline park, having the time of their lives, 80s vintage photo”

Camera and Lens Simulation

Be specific about camera settings for authentic results:

Shot on Hasselblad X2D, 80mm lens, f/2.8, natural lighting

Canon 5D Mark IV, 24-70mm at 35mm, golden hour, shallow depth of field

Multi-Reference Image Editing

*[pro] API has a 9MP total limit for input+output. At 1MP output you can use up to 8 reference images, at 2MP output up to 7, and so on.

Multi-reference is powerful for:

• Fashion shoots: Combine clothing items into styled outfits
• Interior design: Place furniture and decor in rooms
• Product composites: Combine multiple products in scenes
• Character consistency: Maintain identity across variations

Fashion Editorial Example (8 references)

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.”

For multi-reference editing, describe how each input should be used. The model combines clothing items, accessories, and style references into a cohesive scene based on your prompt.

Prompt Upsampling

FLUX.2 offers a prompt_upsampling parameter that automatically enhances your prompt for better results. 

• Quick iterations without crafting detailed prompts
• Exploring creative variations
• When you have a basic concept but want richer output

Prompt upsampling adds detail and context to your prompt automatically. Your original intent is preserved while the model expands on visual elements.
