Red has a dual imagery: On one hand, red symbolizes the shedding of blood and is therefore used on Palm Sunday (when Christ entered Jerusalem to prepare for His death), Good Friday, any other commemoration of the Lord's passion, the votive Mass of the Precious Blood, the days marking the martyrdom of the apostles (except St. John), and the feasts of other martyrs who offered their lives for the faith.On the other hand, red also signifies the burning fire of God's love. For this reason, red vestments are won on Pentecost when the Holy Spirit descended on the apostles and tongues of fire rested on their heads; for the celebration of the Sacrament of Confirmation; and for the votive Masses of the Holy Spirit.
