What the model said

**`#007BFF`** – A clean, modern blue that works great for primary buttons. It has good contrast and is commonly used in modern UI design (Bootstrap's default primary color).

If you want alternatives:
- **`#28A745`** – Green for positive/success actions
- **`#FF6B6B`** – Red for destructive/warning actions  
- **`#6C757D`** – Gray for secondary buttons

The blue is a safe choice for general-purpose buttons unless you have a specific action type or design system in mind.
