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 reads as calm without being dull, and it works with nearly everything.

That said, "best" depends on the job: red wins for grabbing attention, green for restfulness, and orange if you just want to be cheerful.
