What a native German speaker would actually say
Both the English and German expressions share the exact same meteorological metaphor: a sudden storm or bolt of lightning appearing in an otherwise cloudless sky. While English reduced the image down to just the color ("the blue"), German preserved the full reference to the clear sky (*heiterer Himmel*). The phrasing *aus heiterem Himmel* matches "out of the blue" perfectly in tone, register, and frequency.
A common pitfall for English learners is confusing this phrase with *ins Blaue hinein*. Although *ins Blaue* uses the color blue, it conveys an entirely different meaning: doing something aimlessly, guessing randomly, or embarking on a journey without a set destination. To say something struck you unexpectedly, *aus heiterem Himmel* or *aus dem Nichts* are the only natural choices.
