Generating Images with Consistent Branding
Create a master prompt for use with an AI image generator such as Nano Banana, to create consistent image branding.
The method
Use the prompts below in an LLM such as ChatGPT. The result will be a master prompt you can then use in an image generator - we recommend Nano Banana inside of Google Gemini 2.5.
The prompts
Understanding Your Branding
I want to create a series of on-brand images using Gemini 2.5 Flash (Nano Banana). Before we create any prompts, let's first build a clear Brand Visual Identity Guide. (Please describe your brand's visual style using the following points):
- Core Mood: Provide 3-5 adjectives that describe the feeling of your brand (e.g., "vibrant, energetic, optimistic" or "calm, minimalist, sophisticated").
- Primary and Secondary Colors: (List your main brand colors. If you have them, please provide specific hex codes for accuracy).
- Key Visual Elements: Describe any recurring subjects, motifs, or styles (e.g., "line art illustrations of nature," "close-up photography of textures," "3D clay-style characters").
- Elements to Avoid: List anything that would feel off-brand (e.g., "no human faces," "avoid dark or moody colors," "no sharp angles").
Based on these details, please write a single paragraph summarizing my brand's visual identity to confirm you understand the style we are aiming for.
Create the Master Prompt
Based on the Brand Visual Identity Guide we just defined, let's create a reusable "Master Prompt Formula" to ensure consistency in every image we generate.
First, establish a "Golden Rule" for our image generation process that captures the most important element of our style.
Next, design the Master Prompt Formula. This formula should be a template with clear placeholders that we can easily fill in for any future image request. It should logically structure the key elements from Prompt 1 to guide the AI effectively.
Create Some Prompts
Now, let's use the "Master Prompt Formula" and "Golden Rule" to generate three specific, ready-to-use prompts for the AI image generator. Create a unique and detailed prompt for each of the following business needs:
- An engaging image for a social media post announcing a new feature.
- A header image for a website blog post about an upcoming company event.
- An abstract background texture for our website's contact page.
Ensure each prompt is fully detailed and perfectly follows the structure of the Master Prompt Formula you created.
