What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or the color of the ocean a few meters down. It's calm without being dull, works with almost everything, and it's the most common favorite color worldwide, so I'm in good company.

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.
