What the model said

Blue — specifically a deep, slightly green-leaning blue like the ocean a little before dusk. It's calm without being dull, it's the most commonly named favorite across cultures, and it works well next to almost anything.

That said, "best" depends on the job: for a terminal theme, I'd argue for a warm amber on dark gray.
