Some churches e.g. Catholic and Anglican, use different coloured robes; the colour depends on the season. Here's an explanation: Red: represents love + fire (feasts of the Holy Spirit) and blood (feasts of saints who were martyred) Purple: represents repentance (used during Lent and possibly Advent) as well as sorrow (used at funerals) Blue: represents motherhood (used on feasts of Mary and in some places also during Advent as a sign of preparing to celebrate the birth of Christ) White: represents joy (used for feasts of Christ, Mary, saints who are not martyrs. Also during Christmas and Easter. May be used for funerals to emphasise the resurrection of the dead). Gold: represents joy and may be used during major celebrations such as on Easter Sunday and Christmas. Black:represents mourning and is used in funerals, depending on (a) culture (b) wishes of the family
