What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or the sky about twenty minutes after sunset. It's the most common favorite color across cultures in surveys, it's calm without being dull, and it works with almost everything.

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