Liturgical colours  Liturgical colours are those specific colours used for vestments and hangings within the context of Christian liturgy. The symbolism of violet, white, green, red, gold, black, rose and other colours may serve to underline moods appropriate to a season of the liturgical year or may highlight a special occasion. There is a distinction between the colour of the vestments worn by the clergy and their choir dress, which with a few exceptions does not change with the liturgical seasons. In the Roman Rite, as reformed by Pope Paul VI, the following colours are used, in accordance with the rubrics of the General Instruction of the Roman Missal, Section 346. On more solemn days, i.e. festive, more precious, sacred vestments may be used, even if not of the colour of the day. Such vestments may, for instance, be made from cloth of gold or cloth of silver. Moreover, the Conference of Bishops may determine and propose to the Apostolic See adaptations suited to the needs and culture of peoples. Ritual Masses are celebrated in their proper colour or in white or in a festive colour. Masses for Various Needs, on the other hand, are celebrated in the colour proper to the day or the season or in violet if they bear a penitential character. Votive Masses are celebrated in the colour suited to the Mass itself or even in the colour proper to the day or the season. Some particular variations:  The rules on liturgical colours in the 1960 Code of Rubrics, whose observance is still permitted in the circumstances indicated in the 2007 document "Summorum Pontificum" on use of the 1962 Roman Missal, which incorporates them, differ from the current rubrics in the following respects:  Pope Pius X raised the rank of Sundays of ordinary time, so that on those that fell within octaves green was used instead of the colour of the octave, as had previously been the rule. The rules on liturgical colours before the time of Pope Pius X were essentially those indicated in the edition of the Roman Missal that Pope Pius V promulgated in 1570, except for the addition of feasts not included in his Missal. The scheme of colours in his Missal reflected usage that had become fixed in Rome by the twelfth century. The Byzantine Rite, which is used by all the member churches of the Eastern Orthodox Church, the Byzantine Lutheran Churches and the Eastern Catholic Churches of Byzantine Rite, does not have a universal system of colours, with the service-books of the Byzantine tradition only specifying "light" or "dark" vestments in the service books.
