What the model said

Blue — specifically a deep, slightly green-leaning blue like teal or cerulean. It's the most common favorite color across cultures, it's easy on the eyes, and it's the color of both clear skies and deep water, which is hard to beat.

That said, "best" depends on the job: orange for visibility, green for calm, red for urgency. If you're picking a color for something specific, tell me what and I'll give you a more useful answer.
