Liturgical colors are specific colors used in Christian worship to symbolize different seasons and occasions in the church calendar. Each color has its own meaning: for example, purple represents penitence and preparation during Advent and Lent, while white signifies joy and celebration during Christmas and Easter. These colors are often displayed on altar cloths, vestments, and other church decorations. Green is used during Ordinary Time, symbolizing growth and life, while red represents the Holy Spirit and is used on Pentecost and for martyrs' feast days. Each color helps convey the themes of the worship service.
