What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or petrol. It's calm without being dull, works in both light and dark contexts, and it's the color most people worldwide name as their favorite, so I'm in good company.

That said, "best" depends on the job: if you're picking a color for something specific (a UI, a terminal theme, a logo), tell me what and I'll give you a more useful answer.
