I just thought i would give a brief summary about the colours that define the liturgical year  of the Church.

White or Gold

Since it is a festive, joyful colour, is used during the Christmas and Easter seasons,  and on major feast days. Because white symbolises the Resurrection, it is also the colour often used for funerals.

Purple or Violet

 Symbolizes repentance and penance.Vestments of purple or violet are used during Lent or Advent.

Green

Is the colour of growth, life and hope. It is worn during ordinary time.

Red

Is the colour that is used on Passion (Palm) Sunday,Pentecost Sunday, and for celebrations of the Sacrament of Confirmation. It is also the colour that has traditionally been associated with martyrs those who have shed their blood for their faith and so it is worn on the feast days of martyrs.

Rose

Rose is an optional colour that may be used on the Third Sunday of Advent and the Fourth Sunday of Lent. On both of these days, the Entrance Antiphon calls us to rejoice, so the rose vestments mark a softening of the penitential tone of the season.
