<P> In 1964, an Advent crown made at home from wire coathangers and tinsel, appeared on the bi-weekly children's TV program Blue Peter . This' make' became one of the program's most iconic, repeated each year, and was the introduction of this tradition to most of the broadly Anglican audience . In later years, the candles were replaced by baubles, out of concern over fire . </P> <P> More recently, some Eastern Orthodox families have adopted an Advent wreath with six candles symbolizing the longer Christmas fast in Orthodox tradition, which corresponds to Advent in Western Christianity . </P> <P> Advent wreaths are circular, representing God's infinite love, and are usually made of evergreen leaves, which "represent the hope of eternal life brought by Jesus Christ ." Within the Advent wreath are candles that generally represent the four weeks of the Advent season as well as "the light of God coming into the world through the birth of Jesus Christ" although each of the candles has its own significance as well; individually, the candles specifically symbolize the Christian concepts of hope (week one), peace (week two), joy (week three) and love (week four) in many traditions . Many Advent wreaths also have a white candle in the centre to symbolize the arrival of Christmastide, sometimes known as the "Christ candle ." It is lit on Christmas Eve or Christmas Day . The Christ candle is coloured white because this is the traditional festal colour in the Western Church . </P> <P> In many Catholic and Protestant churches, the most popular colours for the four surrounding Advent candles are violet and rose, corresponding with the colors of the liturgical vestments for the Sundays of Advent . For denominations of the Western Christian Church, violet is the historic liturgical color for three of the four Sundays of Advent: Violet is the traditional color of penitential seasons . Blue is also a popular alternative color for both Advent vestments and Advent candles, especially in some Anglican and Methodist churches, which use a blue shade associated with the Sarum rite, in addition to Lutheran churches that also implement this practice . One interpretation holds that blue means hope and waiting, which aligns with the seasonal meaning of Advent . Rose is the liturgical color for the Third Sunday of Advent, known as Gaudete Sunday from the Latin word meaning "to rejoice"--also from the first line of the traditional entrance prayer (called the Introit) for the Mass or Worship Service of the third Sunday of Advent; it is a pause from the penitential spirit of Advent . As such, the third candle, representing joy, is often a different color from the other three . </P>
