README Design Strategies
Dark Mode Compatibility
Most developers use dark mode. Design with dark backgrounds or transparent PNGs that look good on both themes.
Minimal and Technical
Developer audiences appreciate clean, technical aesthetics. Use minimal color palettes and subtle tech-themed elements.

Tips for GitHub Visuals
- Keep file sizes small: Large images slow README loading. Use TinyPNG to compress
- Use relative paths: Store images in a docs folder within your repo
- Design for both themes: Test against GitHub light and dark mode
- Include alt text: Add descriptive alt text for accessibility
- Version your images: Include visual assets in version control
