Side note, BLUE is a modern change to the Advent color. Historical tradition indicates PURPLE; penitence.
Introduced by the RCC as BLUE is Mary’s color.
Yes, thanks
Actually, that’s not exactly true. Purple is still the correct liturgical color, but some Modernists have introduced blue for the reasons you mention. It’s not liturgically correct and most churches still use purple (the same vestments they use for Lent). I seem to recall Fr. Z posting about it a couple of times.
