You want your brand’s visuals to stand out, but stock photos and generic graphics just don’t cut it. Creating custom images with a unique look takes time, effort, and usually a designer you don’t have on staff.

What if you could control the exact mood, texture, and style of your images in seconds—right from ChatGPT?

Let’s see how we emulated a solopreneur’s ChatGPT image generation journey and used advanced image prompting to get on-brand graphics for a campaign, without having to hire an artist.

How We Crafted Properly On-Brand Images

We needed eye-catching visuals to showcase the launch of our new wellness course*. We wanted each image to match our brand’s calming, creative vibe—something stock graphics never quite delivered.

By specifying both the “medium” (watercolor painting) and “style” (minimalist, tranquil) in ChatGPT, we generated a set of consistent, professional-looking images for our campaign in minutes.

Why Medium & Style Prompts Work So Well

• Defines the technical form: Specifying the medium (e.g., watercolor, clay, oil painting) gives each image a distinct texture and tone.

• Sets the emotional mood: The style (e.g., film noir, cyberpunk, minimalist) controls the atmosphere, lighting, and visual impact.

• Delivers brand consistency: Mixing medium & style ensures all visuals align with your business’s vibe—no more mismatched graphics.

• Unlocks creative control: You can experiment and iterate quickly, saving hours (and budget) on design cycles.

• Fits any business need: From playful clay art for kids’ brands to dramatic noir for consulting decks, you get exactly the look you want.

How We Did It

Here’s exactly how our fictional freelance coach used ChatGPT to generate campaign-ready images—no design expertise required.

1 – Describe the Scene Clearly

We hit the “Create an image” tool inside of ChatGPT 4o, and started with a simple, clear description of the scene: “A woman meditating on a hill at sunrise.”

2 – Choose the Medium for Texture & Feel

Next, we picked “watercolor painting” as the medium. This created soft, blended textures and a calming mood—perfect for our wellness brand.

3 – Add Style for Mood & Consistency

We layered on the style: “minimalist, tranquil style.”

💫 Level Up

FACT: More than one-third of organizations are already using generative AI to create images, mainly in marketing, product design, and branding roles .

🔹 Ready to design custom brand visuals that actually stand out? Our new course shows you exactly how to turn ideas into polished, consistent images—logos, mockups, transparent assets, and more—using ChatGPT’s built-in tools, step by step.

By the end, you’ll know how to:

• Use a structured prompt formula to guide your AI images

• Control lighting, framing, and style for polished results

• Upload and restyle your own photos or logos

• Create logos, product mockups, stock visuals, marketing graphics

• Generate alt descriptions and optimize images for SEO

• Automate consistent prompt generation using custom GPTs

With one in three businesses already using AI images, now’s the time to start creating standout visuals for your brand, content, and campaigns, without relying on a design team.

4 – Mix and Match for Exploration

Curious about other looks, we swapped in “oil painting” for a richer, more classic vibe, and “digital illustration” for crisp, modern graphics.

5 – Ask ChatGPT for More Options

Whenever we felt stuck, we just prompted: “List 20 different types of mediums an image can be created in.”

ChatGPT gave us a menu of choices—clay art, pencil sketch, collage, and more—making it easy to experiment.

6 – Iterate Until It’s Right

We then combined different mediums and styles, tweaking prompts and previewing results until we had a full set of visuals that felt cohesive and professional.

This entire process took under 30 minutes—no designer needed.

Other Use Cases

Controlling medium and style in ChatGPT image prompts isn’t just for coaches or course creators. It’s a flexible technique that fits almost any business or creative workflow.

• Ecommerce: Show product mockups in clay art, pencil sketch, or photorealistic styles for different marketing channels.

• Consulting: Generate stylized infographics or charts in vintage, futuristic, or minimalist aesthetics for presentations.

• Content Creators: Create on-theme podcast covers, YouTube thumbnails, or blog illustrations with a consistent visual identity.

• Event Planners: Design invitations and social posts in playful, elegant, or retro mediums to match each event’s vibe.

• Agencies: Rapidly prototype visual directions for client pitches by mixing and matching styles and mediums.

This workflow lets any entrepreneur create on-brand, campaign-ready images on demand, saving hours and producing results that are truly unique to their business.

💡Bonus Pro Tips

• Ask for Style Lists: Not sure what’s possible? Prompt ChatGPT for a list of mediums or styles, then copy-paste your favorites into your prompt.

• Combine Multiple Styles: Try prompts like “digital illustration, cyberpunk + surrealist style” to create unique blends that stand out from generic graphics.

• Reference Art Movements: For specific moods, name-drop movements (e.g., “Bauhaus style poster” or “Impressionist painting”) for more precise results.

• Preview & Refine: Generate several images, compare side by side, and tweak your prompt for the best match—small changes make a big difference.
