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 the sky and the sea, and it reads well on both light and dark terminal themes.

That said, it's entirely subjective. If you're picking a color for something specific (a UI, a chart, a brand), tell me the context and I can give a more grounded recommendation.
