Need a logo for your new business, project, or personal brand, but don't have a big budget? In the past, you'd either have to hire an expensive designer or struggle with complicated software. Today, AI-powered logo creation makes it possible to generate stunning designs instantly.

This guide will walk you through the process of designing a unique logo using a text-to-image tool like the Nano Banana AI generator.

1. Brainstorm Your Core Concepts

Before you write a single prompt, think about your brand's identity. What does it represent? Who is your audience? Considering the core principles of effective logo design can be very helpful here. Jot down a few keywords. For example, for "Nano Banana," the concepts might be: "technology," "creativity," "speed," "fun," and of course, "banana."

2. Master the Logo Prompt Formula

Writing a prompt for a logo is different from a general image prompt. You need to be clear and concise. For a deep dive into the fundamentals, check out our guide on how to write prompts for AI. A great formula to start with is:

[Style] logo of a [Subject], [Color Scheme], [Additional Keywords]

Here are the key elements for prompt-based logo design:

• Style: This is crucial. Use keywords like "minimalist vector logo," "vector logo," "flat icon," "modern logo," or "emblem." Using "vector" or "flat" tells the AI to create a clean, scalable graphic suitable for a logo.
• Subject: What is the main visual? A "lightning bolt," an "eagle," an "abstract shape," or a "circuit board banana."
• Color Scheme: Be specific. "vibrant orange and white," "monochromatic blue," "on a plain white background." Requesting a plain background is important for logos.

3. Example Prompts for Logo Design

Let's put the formula into practice. Here are some prompts you could try in an AI logo generator:

Minimalist vector logo of a stylized brain made of circuits, vibrant orange and deep blue, on a plain white background.

Modern flat icon of a soaring eagle, simple lines, black and gold, professional logo design.

Emblem logo for a coffee shop, a steaming mug inside a circle of coffee beans, rustic and brown color palette, vintage style.

4. Iterate and Refine

Your first generation might not be perfect, and that's okay! The power of designing logos with artificial intelligence is in iteration. Take the image you like best and use the image-to-image feature to refine it.

For example, if the AI generates a logo you like but it includes text, you can upload it and use a new prompt like, "remove all the text, make the lines cleaner." If the colors are off, you can say, "change the color to a deep forest green."
