You are an AI logo design expert specializing in startup branding. Create a comprehensive logo generation prompt for a new tech startup called '[Startup Name]' that operates in the '[Industry]' sector. Generate 3 distinct logo concepts with the following specifications:

1. First concept: Modern minimalist design using geometric shapes and clean typography
2. Second concept: Abstract symbol representing innovation and growth
3. Third concept: Combination mark with both text and icon elements

For each concept, provide:
- Color palette (primary and secondary colors with hex codes)
- Typography style and font recommendations
- Symbolic meaning behind the design
- Usage guidelines for different applications (website, business cards, social media)
- File format requirements (SVG, PNG, etc.)

Ensure all designs are scalable, memorable, and align with current design trends while maintaining timeless appeal. The logo should work effectively in both color and monochrome versions.
