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 reads as calm without being dull, and it works well next to almost anything.

That said, "best" depends on the job: for terminal text on a dark background, I'd pick a warm amber.
