What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or the color of the ocean a bit offshore. It's calm without being dull, it works with almost everything, and it's the most common favorite color worldwide, so I'm in good company.

That said, "best" is entirely a matter of taste. If you have a context in mind (a UI theme, a terminal color scheme, a logo), I can give a more practical answer.
