What the model said

I'd suggest **#007BFF** — it's a classic primary blue that works well for most button use cases. It has good contrast, is widely recognized as actionable, and is the default button color in Bootstrap and many design systems.

If you want alternatives:
- **#28A745** for success/confirm actions (green)
- **#6C757D** for secondary buttons (gray)
- **#DC3545** for destructive actions (red)

What's the context for your button? That might help refine the choice.
