What the model said

I'd suggest **#007BFF** for a primary button color. It's a clean, professional blue that works well for call-to-action elements, has good contrast for accessibility, and is widely used as a design standard (Bootstrap's default, for instance).

If you want alternatives:
- **#2563EB** - Modern, slightly brighter blue (Tailwind's blue-600)
- **#10B981** - Green for success/confirmation actions
- **#EF4444** - Red for destructive/danger actions
