BLACK is a liturgical color

Contrary to the rants of the swivel-chair and hobbyist liturgists and ill-informed priests, BLACK is a liturgical color which the Church did not abolish.

The General Instruction of the Roman Missal is specific about this:

346. As regards the color of sacred vestments, traditional usage should be observed, namely:

e) Besides the color violet, the colors white or black may be used at funeral services and at other Offices and Masses for the Dead [emphasis mine]

And here are some photos I got online, of bishops and priests celebrating the Mass of All Souls day in the Ordinary Form (Novus Ordo Missae) or the Missal of Blessed Paul VI, wearing black vestments.

So the next time someone rants about black being not a liturgical color, tell them to

Because they do not teach seminarians to read the GIRM.
