The Church employs in her Divine services the symbolism of colors. The liturgical colors are black, gold, green, purple or violet, red, rose, white, and blue or azure. Colors are symbols of different truths, thoughts, and sentiments. The Divine services are offered for various purposes and in honor of different classes of saints, and each of these is signified by an appropriate color, which is the color of the vestments worn by the officiating priest and his principal assistants, of the veil for covering the chalice used in the Mass, and of the draperies hung in front of the altar and tabernacle.
