What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or cerulean. It's the most commonly named favorite color across cultures, it's easy on the eyes, and it works for both sky and sea.

That said, it's subjective; if you're picking a color for something specific (a UI, a terminal theme, a logo), tell me the context and I'll give you a more useful answer.
