Nano Banana logo prompts (10 templates for original marks)

Back to hub

Logos are hard for image generators because good marks require clean geometry, strong silhouette, and originality.

This page focuses on original logo marks and icons which are often more reliable than perfect typography.

Trademark note: Do not ask for a logo like a famous brand. Use these prompts to generate original concepts.

Quick workflow

1. Start with icon-only marks (no letters).
2. Pick 3-5 candidates.
3. Iterate on one: simplify, improve silhouette, enforce geometry.
4. Explore wordmarks separately if needed.

The logo prompt formula

Concept + Style + Geometry rules + Contrast rules + Output intent

Helpful constraints:

• "icon only, no letters"
• "simple geometry, clean negative space"
• "high contrast black on white"
• "centered, minimal, scalable"

10 copy-paste logo prompts

1) 12 icon concepts (black on white)

Generate 12 original logo mark concepts (icon only, no letters) for a brand about [BRAND CONCEPT]. Simple geometric shapes, clean negative space, high contrast black on white, centered, scalable, minimal details, no text.

2) Circle-based mark (scalable)

Original logo mark for [BRAND CONCEPT], built from circles and arcs only, clean geometry, balanced negative space, black on white, centered, no letters, no text.

3) Grid-based mark (systematic)

Logo icon for [BRAND CONCEPT] designed on a grid, strong silhouette, minimal lines, consistent stroke weight, black on white, no letters, no text.

4) Abstract motion mark

Abstract logo mark representing motion and speed for [BRAND CONCEPT], smooth curves, dynamic but simple silhouette, black on white, icon only, no text.

5) Nature-inspired but modern

Original logo icon inspired by [NATURE ELEMENT], modern geometric style, minimal, clean negative space, scalable, black on white, no text.

6) Trust icon (fintech/security)

Original logo mark for [BRAND CONCEPT] conveying trust and security, shield-like silhouette, minimal geometry, black on white, icon only, no letters.

9) Negative space hidden symbol

Original logo icon for [BRAND CONCEPT] using clever negative space to hide a subtle [HIDDEN SYMBOL], minimal geometry, black on white, no text.

10) Refine a chosen mark (cleanup)

Refine this logo mark into a cleaner version: simplify geometry, align to a grid, improve symmetry, increase contrast, remove tiny details, keep it scalable. Black on white, no extra text.

Troubleshooting (logo-specific)

Problem: looks generic or too detailed. Fix: force fewer shapes.

Problem: symmetry is off or lines wobble. Fix: demand grid alignment and symmetry.

Problem: generator keeps adding text. Fix: hard ban.

Problem: inconsistent icon set. Fix: lock style rules (same stroke weight and corner radius).

FAQ

Q1: Can I generate a logo exactly like an existing brand? A: Do not. That risks trademark infringement. Use original concepts and avoid referencing famous logos.

Q2: Why icon-only first? A: Typography and kerning are harder. Icon-only marks are more reliable.

Q3: How do I choose the best mark? A: Test at small sizes, in one color, on light and dark backgrounds.

Q4: Next steps? A: More templates at /nano-banana-prompts. Generate and iterate at /ai-image-generator.
