"Liturgical Colors" in Episcopal worship signify our place in the Church Year:
WHITE, the color of Jesus’ burial garments, for Christmas, Easter, and other ‘feasts’ or festival days, as well as marriages and funerals.
PURPLE/VIOLET for Advent (or ROYAL BLUE) & Lent (or UNBLEACHED LINEN).
RED is used in Holy Week, the Day of Pentecost, and at ordinations.
GREEN is used during Epiphany and the ‘Ordinary Time’ after Pentecost Sunday.
