Liturgical colours are specific colours used for vestments and hangings within the context of Christian liturgy. The symbolism of violet, blue, 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 seasons of the liturgical year.
A cope (Latin: pluviale ("rain coat") or cappa ("cape")) is a liturgical long mantle or cloak, open at the front and fastened at the breast with a band or clasp. It may be of any liturgical colour.
A cope may be worn by any rank of the Catholic or Anglican clergy, and by licensed lay ministers on certain occasions. If worn by a bishop, it is generally accompanied by a mitre. The clasp, which is often highly ornamented, is called a morse. In art, angels are often shown wearing copes, especially in Early Netherlandish painting.
The liturgical year, also called the church year, Christian year, ecclesiastical calendar, or kalendar, consists of the cycle of liturgical days and seasons that determines when feast days, including celebrations of saints, are to be observed, and which portions of scripture are to be read.
Distinct liturgical colours may be used in connection with different seasons of the liturgical year. The dates of the festivals vary somewhat among the different churches, although the sequence and logic is largely the same.
Catholic liturgy means the whole complex of official liturgical worship, including all the rites, ceremonies, prayers, and sacraments of the Church, as opposed to private or collective devotions. In this sense the arrangement of all these services in certain set forms (including the canonical hours, administration of sacraments, etc.) is meant. Liturgy encompasses the entire service: prayer, reading and proclamation of the scriptures, singing, gestures, movement and vestments, liturgical colours, symbols and symbolic actions, the administration of sacraments and sacramentals.
Printed calendars, in addition to its main function to display dates and related information, usually in a table format, also often contain additional information relevant for specific groups – for instance, a Christian liturgical calendar will show holy days and liturgical colours, while a calendar for amateur astronomers will highlight phases of the moon, conjunctions and eclipses. Calendars for general public may also contain various interesting facts (e.g., associated with anniversaries of important people or important events). Various facts were also printed on the back sides of the sheets of a tear-off calendar. In modern times, calendars may also have a decorative purpose.
