What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or cerulean. It's the most commonly named favorite color across cultures, it's calm without being dull, and it pairs well with almost everything.

That said, "best" depends on the job: for a terminal theme, I'd argue for a warm amber on dark; for a warning, nothing beats red.
