Blue, when referring to something risqué, is not recorded until 1840 and there is little evidence to explain why the colour was chosen. Several theories have been put forward, most often the colour of choice worn by ladies of the night.
Blue in the face, used to describe someone who is frustrated, is first recorded in 1864. Yet earlier it was said to be black and blue in the face, the earlier form seen from 1829.
Once in a blue moon is first used in the modern sense to describe a very long time in an anti-cleric flyer in 1528. But a blue moon is a real astronomical event and occurs, on average, every 33 months.

Blue ribbon is a misnomer used solely in the USA for many years. It was a mis-hearing of ‘blue riband’ and resulted in blue ribbons being awarded as prizes.

Blue Riband was borrowed in the early 20th century from the prize awarded in horse racing.
True blue has been used for centuries, certainly appearing in Chaucer, and likely only through the obvious rhyme. Yet it has not always had the same meaning.

Scream blue murder first appears around the late 19th and early 20th centuries. My research has often seen me reading old newspaper reports and I have often read of someone giving evidence at a trial or inquest and relating how they were first aware of the victim’s distress when they called out ‘you have murdered me’. I always wonder whether that was accepted as evidence as for surely you can’t be guilty of murder, while the victim is still breathing and screaming blue murder.
