Redewendung Herkunft "Blaumachen"

Why do we actually say “make blue”?

Monday is always the worst day at university, right? You're still hanging on about the weekend, which is basically too short, and you're suddenly faced with a ten-hour day. Your fellow student is just as unmotivated as you and asks: “Should we call it a day after the two o’clock seminar and go to the café instead?” The temptation is all too great.

In what context do you use the phrase?

"Bloodlining" is basically a synonym for truancy, i.e. when you simply don't go to school, university or work without any good reason.

How did the phrase come about?

The fact that we don't talk about turning red, yellow or green but rather "turning blue" goes back to Blue Monday. This comes from a time when fabrics were still dyed by hand by dyers. The dyers always had Mondays off because they put the fabrics to be dyed in a dye bath on Sundays and let the colors soak in. The following day the tissue was removed and air dried. When it came into contact with the air, a special color showed a chemical reaction - blue. Since drying took a certain amount of time, the dyers had nothing else to do and were able to turn the wool blue without any stress.
