# Logo Generator / Logo 生成器
[English](#english) | [中文](#中文)
---
## English
Professional SVG logo generator with high-end showcase presentations. Generate 6+ design variants based on product characteristics, then create stunning showcase images with 12 professional background styles.
### About
This skill was created to solve a common problem: generating professional logos quickly without sacrificing quality. Traditional logo design requires extensive back-and-forth with designers, while AI-generated logos often lack the refinement and presentation quality needed for real products.
**Logo Generator** bridges this gap by:
- Applying proven design principles (extreme simplicity, generous negative space, precise proportions)
- Generating multiple variants to explore different directions
- Creating production-ready showcase images with professional backgrounds
- Providing both SVG (editable) and PNG (ready-to-use) formats
Perfect for:
- **Startups** needing a professional logo quickly
- **Developers** building side projects
- **Designers** exploring initial concepts
- **Product teams** iterating on brand identity
The skill leverages Gemini 3.1 Flash Image Preview (Nano Banana) to generate high-end showcase images that look like they came from a professional design studio.
### Features
- **SVG Logo Generation**: Create geometric logos with dot matrix, line systems, and mixed compositions
- **Design Variety**: Generate 6+ distinct variants per request with different pattern types
- **Professional Showcase**: 12 curated background styles (void, frosted, fluid, spotlight, analog liquid, LED matrix, editorial, iridescent, morning, clinical, UI container, Swiss flat)
- **Nano Banana Integration**: High-end showcase images using Gemini 3.1 Flash Image Preview
- **Interactive Previews**: Beautiful HTML showcases with hover effects and smooth transitions
### Installation
#### Method 1: Automatic Installation (Recommended)
```bash
npx skills add https://github.com/op7418/logo-generator-skill.git
```
This will automatically install the skill to the correct directory.
#### Method 2: Git Clone
```bash
git clone https://github.com/op7418/logo-generator-skill.git ~/.claude/skills/logo-generator
```
#### Method 3: Manual Installation
1. Download this repository
2. Copy the `logo-generator` folder to your Claude Code skills directory:
- **macOS/Linux**: `~/.claude/skills/`
- **Windows**: `%USERPROFILE%\.claude\skills\`
3. Ensure the folder structure contains `SKILL.md` and `README.md`
#### Post-Installation Setup
After installation, set up the required dependencies:
```bash
cd ~/.claude/skills/logo-generator
pip install -r requirements.txt
```
Configure your Gemini API key:
```bash
cp .env.example .env
# Edit .env and add your GEMINI_API_KEY
```
Restart Claude Code and verify by typing `/logo-generator` in the conversation.
### Usage
#### Basic Workflow
1. **Start a logo project**:
```
Generate a logo for my AI product called "DataFlow"
```
2. **Provide context** (the AI will ask):
- Industry/Category (e.g., AI, fintech, design tools)
- Core Concept (e.g., connection, flow, security)
- Design Preferences (minimal/complex, cold/warm)
3. **Review variants**: The AI generates 6+ SVG logo variants with design rationale
4. **Select and refine**: Choose your favorite, request adjustments
5. **Generate showcase**: Create professional presentation images with multiple background styles
#### Example Commands
```
Create a logo for a blockchain security platform
Generate 6 logo variants for "CloudSync" - a file sync tool
Show me the logo in different background styles
Export the logo as PNG at 2048x2048
```
### Workflow Phases
**Phase 1: Information Gathering**
Collect product name, industry, core concept, and design preferences
**Phase 2: Pattern Matching & SVG Generation**
- Generate 6+ distinct design variants
- Create interactive HTML showcase
- Explain design rationale for each variant
**Phase 3: Iteration & Refinement**
- Select favorite variants
- Adjust parameters (size, spacing, rotation)
- Combine elements from different variants
**Phase 4: High-End Showcase Generation**
- Export SVG to PNG (1024x1024px)
- Select 4 showcase styles based on product type
- Generate showcase images with Nano Banana
- Create final presentation webpage
**Phase 5: Delivery**
- Interactive HTML showcase page
- SVG files (editable vector format)
- PNG exports (various sizes)
- Showcase images (4 professional backgrounds)
### Background Styles
#### Dark Styles (6)
- **The Void** - Absolute black with silver micro noise (hardcore tech)
- **Frosted Horizon** - Titanium gray with organic texture (premium products)
- **Fluid Abyss** - Deep purple with fluid fusion (AI-native)
- **Studio Spotlight** - Carbon gray with editorial lighting (magazine quality)
- **Analog Liquid** - Metallic shimmer on solid color base (creative brands)
- **LED Matrix** - Digital retro with glowing dots (cyberpunk)
#### Light Styles (6)
- **Editorial Paper** - Off-white with paper texture (humanistic brands)
- **Iridescent Frost** - Silver-gray with holographic hints (tech hardware)
- **Morning Aura** - Warm ivory with pastel colors (approachable AI)
- **Clinical Studio** - Pure white with geometric shadows (algorithm-driven)
- **UI Container** - Frosted glass container effect (SaaS platforms)
- **Swiss Flat** - Pure solid color, zero effects (timeless authority)
### Design Principles
1. **Extreme Simplicity** - 1-2 core elements maximum
2. **Generous Negative Space** - At least 40-50% empty canvas
3. **Precise Proportions** - Line weights 2.5-4px, proper spacing
4. **Visual Tension** - Intentional asymmetry creates interest
5. **Restraint Over Decoration** - Every element must justify its existence
6. **Single Focal Point** - Clear visual hierarchy
