Logo Design Prompt Prompt for Nano Banana (Gemini)
This is the Nano Banana (Gemini) version of the logo design prompt prompt: minimal logo concepts with flat vector style and clean negative space. It is formatted the way Nano Banana (Gemini) takes prompts best. Free — copy it, replace the bracketed parts, and paste it in.
The prompt
Push copies this prompt with a reference line naming your image, and downloads the image file — attach it in the model to complete the pair. This page stages the pair for you; it cannot upload into the model itself (sites cannot reach into each other), so the final attach happens there. The image is downscaled to at most 1024px and stored only in this browser, paired with this prompt. If browser storage is full, it is kept for this visit only.
Using this prompt with Nano Banana (Gemini)
Nano Banana is Google's Gemini image family (the current flagship is the Gemini 3 Pro Image model). It takes conversational natural-language prompts — describe the image the way you would to a person, state the aspect ratio and resolution in prose or the app controls, and refine in follow-up turns: editing is multi-turn, so describe the change instead of rewriting the whole prompt. It accepts many reference images in one prompt (up to 14) — attach your keyframe and say what it controls. There is no negative-prompt field: to exclude something, describe what the image should show instead, or state the exclusion plainly in the instruction.
What this route costs — and how to pay less
Cost structure: bundled into Google's Gemini app and AI subscription plans (image generation included, with higher tiers raising limits), or metered per image through the Gemini API. If you already pay for a Google AI plan, this route may cost you nothing extra per image. The same prompt is pre-configured in this library for every major model, so you can run it on whichever route fits your budget — comparing the structures before you generate is a free way to save money.
Replace the bracketed placeholders — [BRAND NAME OR FIELD], [SYMBOL IDEA], [COLORS] — with your own details before pasting.
