Liturgies celebrated during the different seasons of the liturgical year have distinctive music and specific readings, prayers, and rituals. All of these work together to reflect the spirit of the particular season. The colours of the vestments that the priest wears during the liturgy also help express the character of the mysteries being celebrated.
On more solemn days, festive, that is, more precious, sacred vestments may be used, even if not the colour of the day.
White is used during Easter and Christmas time; also on celebrations of the Lord (other than of his Passion), of the Blessed Virgin Mary, of the Holy Angels, and of Saints who were not Martyrs; on the solemnities of Most Holy Trinity, All Saints (1 November) and of the Nativity of Saint John the Baptist (24 June); and on the feasts of Saint John the Evangelist (27 December), of the Chair of Saint Peter (22 February), and of the Conversion of Saint Paul (25 January). It may in England and Wales be used for Funerals.
Red denotes the Passion of the Lord (Palm Sunday and Good Friday), the Holy Spirit (Pentecost) and the celebrations of martyrs.
Green is used during Ordinary Time.
Purple OR VIOLET
Purple or Violet vestments are worn during Advent and Lent and for Funerals. In some places purple, seen more as symbolic of hope and joy, is worn in Advent and for funerals whilst violet is kept for the penitential time of Lent.
Rose may be used on Gaudete Sunday (Third Sunday of Advent) and on Laetare Sunday (Fourth Sunday of Lent).
