What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or petrol. It's calm without being dull, works in both light and dark contexts, and it's the color people across cultures most often name as their favorite, so I'm in good company.

That said, "best" depends on the job: for a terminal theme, a warning label, or a front door, I'd give different answers.
