Best Prompts for Flux Kontext
Image generated with Flux Kontext on NightCafe
Flux Kontext is an incredibly powerful AI tool for editing images using natural language — but its real magic comes out when you know how to write great prompts.
Whether you’re refining character details, adding background elements, or removing unwanted objects, the quality of your edit prompt determines how successful your result will be.
This guide shares the best types of prompts to use with Flux Kontext, along with examples and expert tips to help you get better, faster results.
📌 What Makes a Good Flux Kontext Prompt?
Flux Kontext is instruction-based — that means it works best when you give it clear, actionable directions. The AI looks at your original image and applies changes in context, preserving the layout, style, and important elements.
Good prompts typically have three key traits:
Specific — clearly describe what you want to change
Targeted — mention the subject or part of the image to edit
Simple — one instruction at a time works best
🧠 Types of Prompts That Work Well
1. Object Additions
Tell the model to insert something new.
“Add a dragon flying in the sky”
“Place a sunflower in the character’s hand”
“Add a coffee cup on the table”
✅ Tip: Flux Kontext preserves lighting and style, so added objects blend naturally.
2. Appearance Changes
Modify colors, materials, or attributes of existing items.
“Change the woman's hair to silver”
“Make the jacket leather instead of denim”
“Turn the sky red at sunset”
✅ Tip: Use adjectives to guide the mood (e.g. “gritty,” “pastel,” “futuristic”).
3. Removals and Cleanups
Use Flux Kontext to erase elements.
“Remove the person in the background”
“Erase the text on the sign”
“Delete the second tree on the left”
✅ Tip: These work best when the object you want to remove is clearly visible.
4. Lighting and Atmosphere
Flux Kontext is great at changing ambiance and mood.
“Make it nighttime with glowing streetlights”
“Add fog to the scene”
“Change the lighting to warm and golden”
✅ Tip: Try using lighting prompts before character or color changes.
5. Character Edits and Consistency
Modify character features while keeping their identity. To keep the character’s identity consistent, it’s important to include something like “maintain the exact same character and facial features” in the prompt.
“Make the character smile, maintain the exact same character and facial features”
“Change the outfit to a business suit, maintain the exact same character and facial features”
“Add a hat to the character, maintain the exact same character and facial features”
✅ Tip: Flux Kontext is better than most models at maintaining character identity across edits.
🛑 What to Avoid
❌ Overly complex instructions: Break big ideas into smaller edits
❌ Ambiguous wording: Avoid “make it better” or “change stuff”
❌ Contradictory edits: Don't ask to remove and change the same object in one go
🧪 Bonus: Chain Prompts for Iterative Editing
Want to make complex transformations? Try editing in stages:
First prompt: “Add a medieval castle in the background”
Second prompt: “Make it night with torches lit”
Third prompt: “Add a knight on horseback in front of the castle”
Each prompt builds on the previous result while maintaining consistency.
✅ Final Thoughts
Mastering prompt writing is the key to unlocking the full potential of Flux Kontext. Start small, be clear, and experiment with single edits at a time — and you’ll be amazed at how precise and creative your results can be.
Platforms like NightCafe make this process even easier, letting you apply these prompts directly to your images with no technical setup.
