Symbol-wise:
"It's not a Christmas tree, it's an Advent tree, it's decorated in purple."
"It's not a Christmas wreath, it's an Advent wreath. It has four candles, three in purple, 1 in pink rose, we'll light up one candle each week."
"Purple used to be THE royal color."
Btw, the whole family will have a Christmas Eve by the beach this year. Couldn't wait, couldn't wait.
