What the model said

I'd suggest **#007BFF** — it's a professional blue that works well for primary action buttons. It has good contrast on light backgrounds and is widely used in modern interfaces (it's Bootstrap's standard primary color).

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