What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or cerulean. It's the most commonly named favorite color worldwide, it's easy on the eyes, and it reads well in both light and dark contexts.

That said, "best" depends on the job: red for urgency, green for "all tests passed," and amber for a terminal with character.
