White is the colour of purity and innocence and is worn on the feast days of Our Lord, the Holy Virgin Mary, the angels and the saints who are not martyrs.
Red symbolises fire and blood, and is the colour of martyrdom, the Holy Ghost, the Crucifix and the apostles. Although never worn for extended periods, the colour red is seen throughout the year, and denotes individual feast days.
Green represents life. It is present on ordinary Sundays, and after Epiphany and Pentecost.
Purple is the symbol of quietness and penitence. Violet is worn on the Sundays and weekdays of Advent, during Lent, on feast days at the beginning of each season, before a period of fasting and on pilgrimages.
Black is the colour of mourning worn on Good Friday, on All Souls Day and at masses for the dead.
Pink marks the pauses for joy during periods of penitence and fasting.
Gold is permitted on holidays and can replace white, red and green but never black.
