What the model said

I'd recommend **#007BFF** for a primary button. It's a clear, professional blue that works well across most interfaces and has good contrast for accessibility.

If you need alternatives depending on your use case:
- **#28A745** (green) - for success/confirm actions
- **#DC3545** (red) - for destructive/delete actions  
- **#6C757D** (gray) - for secondary/cancel actions
- **#6F42C1** (purple) - for a modern, distinctive look

What's the context for your button? I can suggest something more tailored if you share details about the action or design system.
