Meaning

"Out of the blue" means suddenly and with no warning. Something happens that you didn't expect at all: a message from someone you haven't heard from in years, a job offer, a strange noise at night. The picture is a clear blue sky. Nothing is there, and then, from nowhere, something appears, like thunder on a sunny day.

It is neutral and very common, good for stories, work and casual talk. You'll often hear it after verbs like "call", "show up", "text", "happen" and "come". It's not only for bad news. A surprise gift can arrive out of the blue too. The phrase usually comes last in the sentence, or first for drama: "Then, out of the blue, the lights went off."
