345. Diversity of color in the sacred vestments has as its purpose to give more effective expression even outwardly whether to the specific character of the mysteries of faith to be celebrated or to a sense of Christian life’s passage through the course of the liturgical year.
You might be surprised on two facts here.
First, the Church permits colors other than the Big Four. The Roman approach would probably embrace something thoughtfully chosen, but not out-of-character for the season. “White” feasts have greatest leeway.
These colors are assigned to vestments. Not other decorations in the church building. Obviously, the overall use of color should be harmonious. But there’s nothing in the GIRM to suggest that, say, blue, silver and black wouldn’t complement Advent purple or red and brown don’t make good supportive colors for the Lent shade.
If you don’t have an ordo handy to tell your clergy how to vest, GIRM 346 tells it:
346. As regards the color of sacred vestments, traditional usage should be observed, namely:
a) The color white is used in the Offices and Masses during Easter Time and Christmas Time; on the Solemnity of the Most Holy Trinity; and furthermore on celebrations of the Lord other than of his Passion, celebrations of the Blessed Virgin Mary, of the Holy Angels, and of Saints who were not Martyrs; on the Solemnities of All Saints (November 1) and of the Nativity of St. John the Baptist (June24 ); and on the Feasts of St. John the Evangelist (December 27), of the Chair of St. Peter (February 22), and of the Conversion of St. Paul (January 25).
b) The color red is used on Palm Sunday of the Lord’s Passion and on Friday of Holy Week (Good Friday), on Pentecost Sunday, on celebrations of the Lord’s Passion, on the “birthday” feast days of Apostles and Evangelists, and on celebrations of Martyr Saints.
c) The color green is used in the Offices and Masses of Ordinary Time.
d) The color violet or purple is used in Advent and Lent. It may also be worn in Offices and Masses for the Dead.
You knew that white, black, or violet are all okayed for funerals, right:
e) Besides the color violet, the colors white or black may be used at funeral services and at other Offices and Masses for the Dead in the Dioceses of the United States of America.
f) The color rose may be used, where it is the practice, on Gaudete Sunday (Third Sunday of Advent) and on Laetare Sunday (Fourth Sunday of Lent).
g) On more solemn days, festive, that is, more precious, sacred vestments may be used even if not of the color of the day.
And what would such solemn or festive days be? Parish and diocesan feasts. Special votive Masses. White feasts, certainly.
Metallic hues are fine for the US:
h) The colors gold or silver may be worn on more solemn occasions in the Dioceses of the United States of America.
What about your country?
347. Ritual Masses are celebrated in their proper color, in white, or in a festive color; Masses for Various Needs, on the other hand, are celebrated in the color proper to the day or the time of year or in violet if they have a penitential character, for example, nos. 31, 33, or 38; Votive Masses are celebrated in the color suited to the Mass itself or even in the color proper to the day or the time of the year.
Thoughts, observations, and especially opinions about any or all of this?
