What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or the sky about twenty minutes after sunset. It's the most common favorite color worldwide, it's calming without being dull, and it works with nearly everything.

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