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, and it's rare enough in nature (very few true blue pigments exist) to feel a little special.

That said, "best" is a matter of taste, so if you're picking a color for something specific, like a UI theme or a terminal palette, tell me the context and I'll give you a more useful answer.
