What the model said

I'd suggest **#007BFF** (a vibrant blue) for a primary button. It's:
- **Accessible** with good contrast against white backgrounds
- **Universally recognized** as an interactive element
- **Professional** and widely used in modern UI

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

What context is this button for? That might help narrow down a better choice.
