What the model said
For a primary button, I'd suggest **#0066cc** — a clean, accessible blue that works well for most interfaces and meets WCAG contrast requirements. If you need a different style, let me know: green (#28a745) for success/confirm actions, red (#dc3545) for destructive actions, or gray (#6c757d) for secondary buttons.
