--- name: logo-design-guide description: "Logo design principles and AI image generation best practices for creating logos. Covers logo types, prompting techniques, scalability rules, and iteration workflows. Use for: brand identity, startup logos, app icons, favicons, logo concepts. Triggers: logo design, create logo, brand logo, logo generation, ai logo, logo maker, icon design, brand mark, logo concept, startup logo, app icon logo" allowed-tools: Bash(infsh *) --- # Logo Design Guide Design effective logos with AI image generation via [inference.sh](https://inference.sh) CLI. ## Quick Start ```bash curl -fsSL https://cli.inference.sh | sh && infsh login # Generate a logo concept infsh app run falai/flux-dev-lora --input '{ "prompt": "flat vector logo of a mountain peak with a sunrise, minimal geometric style, single color, clean lines, white background", "width": 1024, "height": 1024 }' ``` > **Install note:** The [install script](https://cli.inference.sh) only detects your OS/architecture, downloads the matching binary from `dist.inference.sh`, and verifies its SHA-256 checksum. No elevated permissions or background processes. [Manual install & verification](https://dist.inference.sh/cli/checksums.txt) available. ## Logo Types | Type | Description | When to Use | Example | |------|-------------|-------------|---------| | **Wordmark** | Company name styled as logo | Strong brand name, short (< 10 chars) | Google, Coca-Cola | | **Lettermark** | Initials only | Long company name, formal | IBM, HBO, CNN | | **Pictorial** | Recognizable icon/symbol | Universal brand, works without text | Apple, Twitter bird | | **Abstract** | Geometric/non-literal shape | Tech companies, conceptual brands | Nike swoosh, Pepsi | | **Mascot** | Character illustration | Friendly brands, food/sports | KFC Colonel, Pringles | | **Combination** | Icon + wordmark together | New brands needing both recognition and name | Burger King, Adidas | ## Critical AI Limitation **AI image generators cannot reliably render text.** Letters will be distorted, misspelled, or garbled. Strategy: 1. Generate the **icon/symbol only** with AI 2. Add text/wordmark in a design tool (Figma, Canva, Illustrator) 3. Or use a combination approach: AI icon + manually set typography ## Prompting for Logos ### Keywords That Work ``` flat vector logo, simple minimal icon, single color silhouette, geometric logo mark, clean lines, negative space design, line art logo, flat design icon, minimalist symbol ``` ### Keywords That Fail ``` ❌ photorealistic logo (contradiction — logos aren't photos) ❌ 3D rendered logo (too complex, won't scale down) ❌ gradient logo (inconsistent results, hard to reproduce) ❌ logo with text "Company Name" (text rendering fails) ``` ### Prompt Structure ``` flat vector logo of [subject], [style], [color constraint], [background], [additional detail] ``` ### Examples by Logo Type ```bash # Abstract geometric infsh app run falai/flux-dev-lora --input '{ "prompt": "flat vector abstract logo, interlocking hexagonal shapes forming a letter S, minimal geometric style, single navy blue color, white background, clean sharp edges" }' # Pictorial nature infsh app run falai/flux-dev-lora --input '{ "prompt": "flat vector logo of a fox head in profile, geometric faceted style, orange and white, minimal clean lines, white background, negative space design" }' # Mascot style infsh app run bytedance/seedream-4-5 --input '{ "prompt": "friendly cartoon owl mascot logo, simple flat illustration, wearing graduation cap, purple and gold colors, white background, clean vector style" }' # Tech abstract infsh app run xai/grok-imagine-image-pro --input '{ "prompt": "minimal abstract logo mark, interconnected nodes forming a brain shape, line art style, single teal color, white background, tech startup aesthetic" }' ``` ## Scalability Rules A logo must work at every size: | Context | Size | What Must Work | |---------|------|----------------| | Favicon | 16x16 px | Silhouette recognizable | | App icon | 1024x1024 px | Full detail visible | | Social avatar | 400x400 px | Clear at a glance | | Business card | ~1 inch | Clean print reproduction | | Billboard | 10+ feet | No pixelation, simple enough | ### Scalability Checklist - [ ] Recognizable as a 16px favicon (squint test) - [ ] Works in single color (black on white) - [ ] Works inverted (white on black) - [ ] No tiny details that disappear at small sizes - [ ] No thin lines that vanish when shrunk - [ ] Clear silhouette without color ## Color Guidelines - **Maximum 2-3 colors** for the primary logo - Must work in **single color** (black, white, or brand primary) - Consider **color psychology**: - Blue: trust, professional (finance, tech, healthcare) - Red: energy, urgency (food, entertainment, retail) - Green: growth, nature (health, sustainability, finance) - Orange: friendly, creative (startups, youth brands) - Purple: luxury, wisdom (beauty, education) - Black: premium, elegant (fashion, luxury, tech) - Test on both light and dark backgrounds ## Iteration Workflow ```bash # Step 1: Generate 5-10 broad concepts for i in {1..5}; do infsh app run falai/flux-dev-lora --input '{ "prompt": "flat vector logo of a lighthouse, minimal geometric, single color, white background" }' --no-wait done # Step 2: Refine the best concept with variations infsh app run falai/flux-dev-lora --input '{ "prompt": "flat vector logo of a geometric lighthouse with light beam rays, minimal line art, navy blue, white background, negative space design" }' # Step 3: Generate at high resolution for final infsh app run bytedance/seedream-4-5 --input '{ "prompt": "flat vector logo of a geometric lighthouse with radiating light beams, minimal clean design, navy blue single color, pure white background", "size": "2K" }' # Step 4: Upscale for production use infsh app run falai/topaz-image-upscaler --input '{ "image": "path/to/best-logo.png", "scale": 4 }' ``` ## Common Mistakes | Mistake | Problem | Fix | |---------|---------|-----| | Too much detail | Loses clarity at small sizes | Simplify to essential shapes | | Relies on color | Fails in B&W contexts | Design in black first | | Text in AI generation | Garbled/misspelled letters | Generate icon only, add text manually | | Trendy effects (glows, shadows) | Dates quickly, reproduction issues | Stick to flat, timeless design | | Too many colors | Hard to reproduce, expensive printing | Max 2-3 colors | | Asymmetric without purpose | Looks unfinished | Use intentional asymmetry or stay balanced | ## File Format Delivery | Format | Use Case | |--------|----------| | SVG | Scalable vector, web, editing | | PNG (transparent) | Digital use, presentations | | PNG (white bg) | Documents, email signatures | | ICO / Favicon | Website favicon (16, 32, 48px) | | High-res PNG (4096px+) | Print, billboards | Note: AI generates raster images (PNG). For true vector SVG, use the AI output as a reference and trace in a vector tool, or use AI-to-SVG conversion tools. ## Related Skills ```bash npx skills add inference-sh/skills@ai-image-generation npx skills add inference-sh/skills@prompt-engineering ``` Browse all apps: `infsh app list`
