== Meaning of blue ==
The color blue is sometimes associated with [[sadness]], which may be where the name of the music style [[Blues|The Blues]] comes from.
Blue is a color of the Jewish religion.
In Western cultures since the 1940s, blue is associated with men/boys, while [[pink]] is associated with women/girls. Before the 1940s, it was the other way around in some countries, so blue was for women/girls and pink was for men/boys. Nobody knows exactly why it changed.<ref>{{cite web|url=https://www.theguardian.com/theguardian/2009/dec/12/pinkstinks-the-power-of-pink|title=The power of pink|first=Jon|last=Henley|date=12 December 2009|publisher=|via=www.theguardian.com}}</ref><ref>{{cite news|url=https://www.nytimes.com/2006/12/24/magazine/24princess.t.html|title=What's Wrong With Cinderella?|first=Peggy|last=Orenstein|newspaper=The New York Times |date=24 December 2006|publisher=}}</ref>
