Advent is a special time of preparation in the liturgical year, focusing our hearts on the celebration of Jesus’ birth in Bethlehem as well as looking forward to when Jesus will come again. To remind us of these and many other spiritual truths, the Church has chosen the color violet to be the primary color of Advent.
Violet has a long history and was a rare color in the ancient world, not easily made into dye that could be used with clothing. While it was traditionally connected to kings and royalty, it also became associated with penance, making it a somber color and chosen by the Church for penitential seasons.
In an issue of The American Ecclesiastical Review (printed in 1902), the author gives a unique explanation behind the reason why violet and rose were chosen for Advent.
