What the model said

I'd suggest **#3498DB** – a friendly, accessible blue that works well for primary action buttons. It has good contrast against both light and dark backgrounds and conveys action/interactivity without being too aggressive.

If you need something different, let me know: danger buttons often use red like #E74C3C, secondary buttons work with gray like #95A5A6, or you could go with a brand color if you have one in mind.
