where is the color purple playing on christmas day

You might be thinking of the term "purple Christmas," which refers to the rare occasion when snow falls on Christmas Day. Purple is often associated with the winter season, and a white snow-covered landscape can give the impression of a purple sky at sunset. So, in a way, the color purple can be a part of a Christmas day that features snow. However, it's not a common occurrence and is more of a poetic or metaphorical reference rather than an actual visual phenomenon.
