What the model said

Blue — specifically a deep one, like the sky about twenty minutes after sunset. It's the most common favorite color worldwide, it's calming without being dull, and it rarely clashes with anything.

That said, "best" depends on the job: for a warning sign it's red, and for a terminal theme it's whatever you can read at 2 a.m.
