SVG Structure:
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 200" width="200" height="200">
<defs>
<!-- Gradients, patterns, filters -->
<linearGradient id="gradient1" x1="0%" y1="0%" x2="100%" y2="100%">
<stop offset="0%" style="stop-color:#4F46E5;stop-opacity:1" />

Create variations exploring different visual approaches:
For each concept, create multiple layout options:
Create professional, optimized SVG code:
Best Practices:

# Logo Design Concepts
## Concept 1: [Concept Name/Theme]
### Design Rationale
[Explain the thinking behind this design, visual metaphors used, and how it represents the brand]
### Primary Logo (Horizontal)
```xml
<svg><!-- SVG code here --></svg>
Usage: Headers, website navigation, business cards Dimensions: 200×60px (scalable)
<svg><!-- SVG code here --></svg>
Usage: Social media profiles, mobile apps Dimensions: 100×120px (scalable)
<svg><!-- SVG code here --></svg>
Usage: Favicon, app icon, small spaces Dimensions: 64×64px (scalable)
Full Color:
Monochrome (Dark):
Monochrome (Light):
Reversed:
[Repeat structure for additional concepts]
### Phase 6: File Generation
Save SVG files with proper naming:
```javascript
// File naming convention
company-name-logo-concept1-horizontal.svg
company-name-logo-concept1-vertical.svg
company-name-logo-concept1-icon.svg
company-name-logo-concept2-horizontal.svg
// etc.
Use the Write tool to save each variation:
// Example
Write({
file_path: "./logos/acme-logo-concept1-horizontal.svg",
content: svgCode
});
Provide comprehensive usage documentation:
# Logo Usage Guidelines
## File Formats Provided
### SVG (Scalable Vector Graphics)
- **Use for:** Websites, digital applications, large prints
- **Benefits:** Infinitely scalable, small file size, editable
- **How to use:** Embed directly in HTML or open in design tools
### Exporting to PNG
If you need PNG format:
**Option 1: Using Inkscape (Free)**
```bash
inkscape logo.svg --export-png=logo.png --export-width=1000
Option 2: Using ImageMagick
convert -background none logo.svg logo.png
Option 3: Online Converter
Maintain minimum clear space around logo:
Website Headers:
Social Media:

<!-- Inline SVG (Recommended for control) -->
<svg><!-- SVG code --></svg>
<!-- Image tag (Simpler) -->
<img src="logo.svg" alt="Company Name Logo" />
<!-- CSS Background -->
.logo {
background-image: url('logo.svg');
background-size: contain;
}
.logo {
width: 100%;
max-width: 200px;
height: auto;
}
/* Mobile */
@media (max-width: 768px) {
.logo {
max-width: 150px;
}
}
