Out of the blue ?!?!?!

Spectators and fans who have been watching the Olympic Games are getting lots of good and bad surprises while their  " heroes and heroines "are performing their sports.

Some of these athletes suddenly fall ,break their limbs or are expelled from their competitions ! Others do not perform as well as they should.Then they make  the crowds boo and complain about teams and groups which had poor disappointing  performances.

Accidents happen out of the blue ,I mean, unexpectedly  in the middle of the athletes' shows ! The audiences react  at once ! Most of the times spectators try to show and give emotional support to these contestants who could not complete their routines and competitions.What else can people do ?

Were you watching any performance or competition when an accident happened  out of the blue ?  Do you know any other idiom in english with a colour in it like " out of the blue " ?
