Black, Violet, and Blue

Pope Cope

In digging around some of my liturgical textbooks, I came across Martin Dudley's entry on liturgical colors in The New Westminster Dictionary of Liturgy and Worship (which, in my humble opinion, should be a required text for anyone involved in liturgical planning). He remarks on the connection between blue, violet, and black vestments:

Black, violet, and blue seem to be interchangeable in the medieval palette, and black was used in Jerusalem in Advent and on Christmas Eve instead of violet and was also assigned to feasts of the Blessed Virgin Mary. This is perhaps part of the development of blue as Mary's colour, as found in Cologne.

Those who argue for certain Marian overtones -- or at least a connection between the colors of Advent and Marian feasts -- do have some room to argue from Tradition, my own misgivings notwithstanding.

Later in the entry, Dudley points to differences between purple: purpureus indicates the "red-purple" and violaceus a "blue-purple." Such distinction does survive today in the General Instruction of the Roman Missal, if memory serves.

Which brings me to a point of minutiae: I tend to call the liturgical color "purple," but properly it is called "violet." From Pfatteicher's Commentary on the Lutheran Book of Worship:

The drafters of the Commons Service Book  and the Service Book and Hymnal knew the tradition out of which they came and so specified "violet" as the proper color for Advent and Lent, translating  violaceus of the Roman rubrics. The name, in Latin and in English, was intended to describe a blue-purple. The editors of the Lutheran Book of Worship, bowing to prevailing popular practiced, used "purple" to describe the color rather than "violet," but the book encourages the use of blue, listing it first.
