    }
}

You can include JSON data directly in the prompt, or convert it into natural language. FLUX.2 supports both formats.

Hexadecimal Color Code Prompting

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

Basic Syntax

Use keywords such as "color" or "hex", followed by the code, to indicate a hexadecimal color:

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

Gradient Colors

Apply a gradient by specifying a starting color and an ending color:

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” "There is a vase on the living room table. The vase is a gradient color, starting from #02eb3c and ending at #edfa3c. The flowers in the vase are #ff0088."

Colors in JSON Prompts

Combine hexadecimal 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"
}

{
    "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"
}

Hexadecimal codes work best when explicitly associated with a specific object. Vague descriptions such as "use #FF0000 somewhere" may lead to inconsistent results.

Infographics and Data Visualization

FLUX.2 can generate charts with clear typography and well-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"
}

{
    "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"
}

Prompt example:

"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." "Create a vertical infographic about global coffee consumption. Title: 'Global Coffee Culture'. Include three sections, each displaying statistics, use an icon for each country, color scheme #4A2C2A (brown) and #F5E6D3 (beige). Adopt a modern minimalist style with clean typography."

Typography and Design

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

Product Advertisement: "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" "Samsung Galaxy S25 Ultra product advertisement, headline 'Ultra-strong titanium', subheadline 'A sturdy titanium frame keeps your Galaxy S25 Ultra protected at all times', close-up of the phone edge showing the 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" "Women's Health magazine cover, April 2025 issue, headline 'Spring Returns', a woman in a green outfit sitting on orange blocks, wearing white sneakers, feature article 'COVID-19: Five Years Later', callout '15 Skincare Habits', professional editorial photography, magazine layout containing multiple text elements"

Multilingual Prompting

FLUX.2 has excellent multilingual understanding. You can prompt in your native language to get 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

Chinese: "At a food market in the Normandy countryside, vendors are selling various vegetables and fruits. At sunrise, the weather is a bit foggy."

Prompting in the native language of the content you are creating often produces more culturally authentic results—local markets, architecture, and atmosphere can be presented more accurately.

Comics and Comic Strips

Multi-Reference Image Editing

*[Pro version] The API has a combined input + output limit of 9MP. With 1MP output, you can use up to 8 reference images; with 2MP output, up to 7, and so on.

The multi-reference feature is very powerful and can be used for:

• Fashion shoots: pairing clothing items into stylish looks
• Interior design: placing furniture and decorations in a room
• Product compositing: combining multiple products into a scene
• Character consistency: maintaining character identity across various variations

Fashion editorial example (8 reference images)

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." "This is a Kodak Ektachrome 64 slide film photograph taken in 1987, using a 35mm spherical lens, aperture f/5.6, cross-processed. In the photo, the model stands in front of a small forest chapel in a forest clearing. The model is dressed in red, standing on the stone steps leading to the wooden chapel, the red clothing contrasting sharply with the weathered brown wood. The background shows a traditional Black Forest chapel—dark wooden structure with a small bell tower, carved wooden door, religious paintings under the eaves, a surrounding clearing full of wildflowers, towering firs forming a natural cathedral, and a small cemetery with a wooden cross. The photo uses a shutter speed of 1/125 second, with dappled forest light at the time of shooting. The cross-processed Ektachrome film shows extreme color shifts—cyan and magenta separation, warm wood tones pushed to orange-brown, reds oversaturated, blacks crushed, highlights blown out, and heavy grain creating a mysterious atmosphere. The composition emphasizes sacred space and pilgrimage. Thomas Struth church interiors, Candida Höfer architectural documentation, religious tourism meets fashion editorial style, and the mystical spirit of the Black Forest."

In multi-reference image editing mode, you need to clearly describe the specific purpose of each reference image. The model can blend clothing items, accessory elements, and style features from different reference images into a coherent, unified scene based on your prompt.

Instant Upsampling

FLUX.2 provides a prompt_upsampling parameter that can automatically optimize your prompt for better results. It is very useful for the following cases:

• Rapid iteration without writing detailed prompts
• Exploring creative variations
• When you have a basic concept but want richer output

Prompt upsampling technology can automatically add detail and context to your prompts. While the model expands visual elements, your original creative intent is fully preserved.

Best Practices Summary

• Control structure: When you need precise control over multiple elements, use JSON-structured prompts. Start simple and gradually increase complexity as needed.
• Be specific with colors: Always associate hex codes with specific objects. "This car's code is #FF0000" works better than "use red #FF0000 in the image."
• Describe what you want: FLUX.2 has no negative prompts. For example, instead of saying "no blur," say "always in sharp focus." Instead of saying "no people," describe an "empty scene."
• Reference cameras and styles: For realistic photographic results, specify the camera model, lens, and film type. "Shot with a Fujifilm X-T5, 35mm f/1.4 lens" produces more realistic results than "professional photo."
• Use your native language: Please describe in the language that best captures the cultural context you need. For example, use French for Paris scenes, and Japanese for anime styles.
• Multi-layer multi-reference carefully: When using multiple input images, clearly describe the role of each image: image 1 represents the subject, image 2 represents the style, and image 3 represents the background.

English original text

    "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.
