What the model said

Here's a solid choice: **#0066CC** (a professional blue)

Other reliable options depending on your use case:
- **#10B981** - green (good for success/confirm actions)
- **#EF4444** - red (good for delete/danger actions)
- **#6366F1** - indigo (modern/trendy)

The blue works well as a default button color since it's familiar and has good contrast on most backgrounds.
