Pink:Rose::Purple:Violet

I think it's time for priests to man up and accept that the colour of the third Sunday of Advent is pink. If it's going to be "rose," then the other three weeks of Advent are "violet." But then we're getting all flowery, and how is that any better than pink and purple? And don't try "light red." Pink is as much light red as purple is blue-ish red. Or reddish blue... though the liturgical purple has more blue than red in the mix.

(Just for clarification for anyone who wishes to forget the pain of analogies: the title of this post is read, "Pink is to Rose as Purple is to Violet.")

Question to readers concerning the order of the candles on the Advent Wreath being lit. Is there a specification that reads that the candles must be lit beginning with the purple one directly across the circle from the pink one, then proceeding in order around the circle to light the pink one last (Fig. 1)? That is how my family and I have traditionally lit ours and seen it lit, but Mother of Sorrows lights theirs with the two next to the pink first, then the pink in the center, then the last purple across from the pink (Fig. 2). Diagrams attempted below for anyone in need of visual aid.

U = Purple
I = Pink
