# Logo Design Guide

Design effective logos with AI image generation via [inference.sh](https://inference.sh) CLI.

## Quick Start

> Requires inference.sh CLI (`belt`). [Install instructions](https://raw.githubusercontent.com/inference-sh/skills/refs/heads/main/cli-install.md)

```bash
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:
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
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 | ~
