AI Logo Design Prompts: A Brand Designer's Playbook for Midjourney and Nano Banana 2

Most AI-generated logos look like logo-shaped objects. They have a mark, some letters, maybe a swoosh, and absolutely none of the discipline that separates a brand identity from a stock graphic. The proportions are slightly off, the type is a fake-looking sans-serif, there are six colors where there should be one, and the whole thing has that unmistakable "AI render of a logo" energy that no serious brand can actually use.

The good news: identity work is one of the categories where 2026 image models genuinely earn their keep — if you prompt them like a brand designer instead of a request form. This playbook is the working version of what I use with founders, agencies and side-project builders shipping real brands with Midjourney V7 and Nano Banana 2.

Why most AI logos look amateur

Type "modern minimalist logo for a coffee shop" into any model and you'll get a beige roundel with a steaming cup, a serif wordmark and a tagline nobody asked for. It reads as AI in under a second. The problem isn't the model — it's the prompt. You've asked for a category and a vibe. You haven't told the model:

• What kind of mark — wordmark, monogram, emblem, abstract symbol, lettermark, combination
• What design references to pull from — Bauhaus, Swiss, art deco, organic, brutalist
• What typography family — geometric sans, humanist sans, transitional serif, slab, script
• What color discipline — single color, two-color, monochrome on white
• What format and use case — app icon, signage, business card, social avatar

Miss those and the model defaults to its safest, most clip-art-adjacent guess. Hit them and it suddenly behaves like a working identity designer.

The five-part logo prompt recipe

Every brand-ready logo prompt I ship has the same five slots. In order:

1. Mark type — "a minimalist geometric monogram", "a vintage badge emblem", "a clean wordmark", "an abstract lettermark combining the letters A and R".
2. Subject / metaphor — "based on a folded paper crane", "inspired by a mountain ridge silhouette", "no pictorial element, type only".
3. Style references — "Swiss design, 1960s corporate identity, Bauhaus geometry" or "art deco, 1920s travel poster" or "hand-drawn, organic, Moonrise Kingdom-era Wes Anderson".
4. Typography — "set in a geometric sans-serif with wide tracking", "a thin neo-grotesque wordmark", "a heavy slab serif lowercase".
5. Format and presentation — "single color on pure white background, vector style, centered composition, generous negative space, suitable for app icon and business card".

Stitched together:

A minimalist geometric monogram combining the letters A and R, inspired by a folded paper crane, Swiss design with 1960s corporate identity influence, set alongside a thin neo-grotesque wordmark with wide tracking, single midnight-navy color on pure white background, vector style, centered composition, generous negative space, suitable for app icon and business card, brand identity presentation

That's the skeleton. Every variable below plugs into one of those five slots.

Mark types — pick one and stay there

Mixing mark types in a single prompt is the fastest way to get garbage. Decide what you're designing before you write the prompt.

• Wordmark — the brand name as the logo (Google, FedEx, Coca-Cola). Best when the name is short and ownable.
• Lettermark — the initials only (HBO, IBM, NASA). Best for long names or acronyms.
• Monogram — interlocked or stacked initials forming a single mark (LV, GG, YSL). Best for fashion, hospitality, premium.
• Pictorial mark — a literal object (Apple, Twitter bird, Target). Best when the object is iconic and memorable.
• Abstract mark — a geometric form with no literal meaning (Nike swoosh, Pepsi globe, Airbnb). Best for tech and modern brands.
• Emblem / badge — type locked inside a shape (Starbucks, Harley-Davidson, NFL). Best for heritage, sports, food and beverage.
• Combination mark — symbol plus wordmark (Adidas, Lacoste, Burger King). Most versatile, hardest to balance.

Name the type explicitly. "A wordmark logo" and "a monogram logo" produce completely different outputs even with identical context.

Style triggers that actually work

Generic style words ("modern", "clean", "professional") do almost nothing. Named design movements and eras pull in real visual references. The triggers below consistently shift the output.

• Swiss / International Typographic Style — "Swiss design, Helvetica, grid-based, asymmetric balance, Müller-Brockmann". For clean, type-led, corporate-confident marks.
• Bauhaus — "Bauhaus geometry, primary colors, circle square triangle, 1920s German design school". For geometric, foundational, almost-toylike marks.
• Art Deco — "art deco, 1920s travel poster, geometric symmetry, stepped forms, gold and black". For luxury, hospitality, cocktail bars.
• Mid-century modern — "mid-century modern, 1960s corporate identity, Saul Bass, Paul Rand, geometric simplicity". For confident, witty, timeless marks.
• Brutalist / Y2K — "brutalist web design, raw geometric forms, monospace type, off-grid composition". For underground, tech, anti-design brands.
• Organic / hand-drawn — "hand-drawn, organic line weight, slight imperfection, ink on paper, indie brand feel". For artisanal, food, beauty.
• Vintage Americana / badge — "vintage Americana badge, 1940s workwear label, distressed texture, heritage brand". For coffee, breweries, outdoor.
• Tech / Silicon Valley — "modern tech logo, geometric sans-serif, abstract mark, gradient-free, app icon ready, Linear-meets-Stripe minimalism". For SaaS, fintech, AI.

Pick one, name it explicitly, and don't combine more than two unless you know exactly why.

Typography language

This is where most AI logo prompts collapse. "With nice typography" means nothing. The model needs a typeface family and a treatment.

• Geometric sans-serif — "set in a geometric sans-serif like Futura or Avenir, wide tracking, all caps". Modern, friendly, slightly retro.
• Neo-grotesque sans — "set in a thin neo-grotesque sans-serif like Helvetica or Inter, tight tracking, lowercase". Clean, corporate, neutral.
• Humanist sans — "humanist sans-serif with open apertures, slight stroke contrast, like Gill Sans or Source Sans". Approachable, editorial.
• Transitional serif — "transitional serif like Baskerville or Plantin, classic proportions". Editorial, premium, heritage.
• Slab serif — "chunky slab serif, heavy weight, like Rockwell or Archer". Confident, food-and-drink, sports.
• Script — "single-stroke script, slightly hand-lettered, like a signature". Beauty, fashion, lifestyle.
• Display / experimental — "custom display lettering, exaggerated proportions, distinctive ligatures". For founder-led, fashion, music.

Always specify case (uppercase, lowercase, sentence case) and tracking (tight, normal, wide). Both meaningfully change the output.

Color discipline

A logo prompt with no color instruction defaults to four-color clip art. Pick one rule and enforce it.

• Single color on white — "single midnight navy on pure white background". The default for identity work. Forces the model to make the shape carry the meaning.
• Two-color palette — "two-color palette: deep forest green and warm cream, no gradients". For brands that need a bit more personality.
• Monochrome black — "pure black on white, no color, no gradients, no effects". The hardest test of a mark — if it works here, it works everywhere.
• Reversed — "white logo on a deep saturated background". For dark-mode or premium presentations.

Always end the color clause with "no gradients, no drop shadows, no glow, no 3D effects, no photo textures". These are the five things models love to add and brand designers immediately strip out.

Copy-paste templates

Five templates I use weekly. Swap the brackets, keep the structure.

Modern tech / SaaS

A clean abstract lettermark combining the letter [X] with a geometric [shape], modern tech logo, geometric sans-serif influence, single [color] on pure white background, vector style, centered composition, generous negative space, app-icon ready, suitable for a [SaaS/fintech/AI] startup, brand identity presentation, no gradients, no drop shadows, no 3D effects

Premium / luxury monogram

An interlocked monogram of the letters [A] and [B], inspired by [art deco / 1920s typography], symmetric and elegant, set in thin gold linework on a deep charcoal background, vector style, centered composition, suitable for a [luxury hotel / fashion house / private members club], brand identity presentation, no gradients, no drop shadows

Heritage badge / emblem

A vintage badge emblem for a [coffee roastery / brewery / outdoor brand] called [Name], type locked inside a [circular / shield / hexagonal] frame, 1940s Americana workwear influence, hand-drawn line work with slight texture, single deep [color] on cream background, centered composition, brand identity presentation, no gradients, no drop shadows

Minimalist wordmark

A minimalist wordmark for [Name], set in a thin neo-grotesque sans-serif with wide tracking, all lowercase, single midnight black on pure white background, vector style, centered composition, generous negative space, Swiss design influence, suitable for a [modern editorial brand], brand identity presentation, no gradients, no drop shadows

Hand-drawn organic mark

A hand-drawn organic pictorial mark of a [subject — a sprig of rosemary / a folded paper boat / a single olive branch], slight ink-on-paper imperfection, paired with a humanist sans-serif wordmark for [Name], single deep [color] on warm off-white background, indie brand feel, suitable for a [small-batch food / beauty / lifestyle] brand, brand identity presentation, no gradients, no drop shadows

Midjourney V7 vs Nano Banana 2 for logos

Both ship usable logos. The sweet spots are different.

Midjourney V7

• Better at: stylized marks, vintage badges, hand-drawn feel, painterly emblems, premium luxury monograms.
• Weaker at: clean typography (it consistently hallucinates fake letterforms), exact letter combinations, perfectly geometric forms.
• Parameters to try: --ar 1:1 --style raw --stylize 100 for clean identity work; push to --stylize 400 for stylized badges and emblems.
• Workflow: generate the mark in Midjourney, then set the wordmark in real typography software. Never trust MJ's letterforms for production.

Nano Banana 2

• Better at: clean geometric marks, more accurate typography, brand-consistent variants across a series, app-icon-ready outputs.
• Weaker at: highly stylized vintage / hand-drawn / textured work; it tends toward smooth and modern.
• How to push it: be more verbose about what not to do — "no gradients, no drop shadows, no photo textures, single solid color, flat vector style".
• Reference images: attach a reference of a logo whose style you want and tell it explicitly to match the approach (not the content).

For most identity projects, generate concepts in both, pick the strongest direction, and finalize the actual production file in Figma or Illustrator. AI is a concepting tool here, not a production tool.

The finishing details that separate AI from brand-ready

Five small additions that consistently move a render from "AI logo" to "could ship":

1. Always specify "vector style". It pushes the model away from photo textures and toward flat, scalable forms.
2. Always end with the "no gradients, no shadows, no 3D" clause. Removes the five most common AI tells in one sentence.
3. Name a real design reference. "In the style of Pentagram's 2010s identity work" or "like a Paula Scher wordmark" pulls in real visual vocabulary.
4. Specify a use case. "App icon ready", "works at 16px and on signage", "suitable for embroidery" — each one constrains the model toward production-ready simplicity.
5. Generate at 1:1 square. Logos are almost always shown in a square container first. Don't fight the format.

If you want the prompt skeleton in a more general-purpose form, the PromptMint AI Prompt Generator will build the full five-part structure from a single line of input. For adjacent commercial work, the AI Product Photography Prompts playbook covers the same discipline applied to physical products, and the Realistic AI Images Guide covers the realism techniques that carry across categories.

A worked end-to-end example

A founder wants an identity for "Northwind" — a small-batch coffee roastery. Same model, same session, three concepts.

Concept 1 — Modern wordmark

A minimalist wordmark for "Northwind", set in a thin neo-grotesque sans-serif with wide tracking, all lowercase, single deep espresso brown on warm cream background, vector style, centered composition, generous negative space, Swiss design influence, suitable for a modern specialty coffee brand, brand identity presentation, no gradients, no drop shadows, no 3D effects --ar 1:1

Concept 2 — Heritage badge

A vintage badge emblem for a coffee roastery called "Northwind", type locked inside a circular frame with a small stylized compass rose at the top, 1940s Americana workwear influence, hand-drawn line work with slight texture, single deep espresso brown on warm cream background, centered composition, brand identity presentation, no gradients, no drop shadows --ar 1:1

Concept 3 — Abstract mark + wordmark

A clean abstract combination mark for "Northwind", a minimal geometric symbol suggesting a curling wind or coffee steam, paired with a thin neo-grotesque wordmark beneath, single deep espresso brown on warm cream background, vector style, centered composition, mid-century modern influence, suitable for a modern specialty coffee brand, brand identity presentation, no gradients, no drop shadows, no 3D effects --ar 1:1

Three concepts, one consistent visual world, ready for a founder review.

The takeaway

Stop prompting logos like a request form. Prompt them like a working brand designer — mark type first, then subject, then a named design reference, then real typography language, then a strict color rule. Lock in one model per project, generate at 1:1, and always strip gradients, shadows and 3D effects. The gap between "AI render of a logo" and "brand-ready identity" is almost entirely in the prompt.
