Install the belt CLI skill: npx skills add belt-sh/cliLogo Design Guide
Design effective logos with AI image generation via inference.sh CLI.
Quick Start
Requires inference.sh CLI (belt). Install instructionsbash
belt login
# Generate a logo concept
belt 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
}'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:
- Generate the icon/symbol only with AI
- Add text/wordmark in a design tool (Figma, Canva, Illustrator)
- 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 symbolKeywords 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
belt 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
belt 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
belt 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
belt 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
belt 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
belt 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
belt 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
belt 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.
