Can blue replace violet as the liturgical
color during Advent?
Blue is not a normal liturgical color
and has only been given special use in Mexico for Marian feasts and is also frequently used in conjunction
with white on Marian feast days elsewhere. Advent is a season of penance, meant to prepare the faithful
for the coming of Christ. There is not any document allowing for the replacement of violet with
blue during Advent.
According to the General Instruction of the Roman Missal:
"Traditional usage should be retained for the vestment colors.
a.White is used in the offices and Masses of the Easter and Christmas seasons; on feasts and memorials of the Lord,
other than of his passion; on feasts and memorials of Mary, the angels, saints who were not martyrs, All Saints
(1 November), John the Baptist (24 June), John the Evangelist (27 December), the Chair of St. Peter
(22 February), and the Conversion of St. Paul (25 January).
b.Red is used on Passion Sunday (Palm Sunday) and Good Friday, Pentecost, celebrations of the Lord's passion,
birthday feasts of the apostles and evangelists, and celebrations of martyrs.
c.Green is used in the offices and Masses of Ordinary Time.
d.Violet is used in Lent and Advent. It may also be worn in offices and Mass for the dead.
e.Black may be used in Masses for the dead.
f.Rose may be used on Gaudete Sunday (Third Sunday of Advent) and Laetare Sunday
(Fourth Sunday of Lent).
The conference of bishops may choose and propose to the Apostolic See adaptations suited
to the needs and cultures of peoples."--n. 308
