Some may be surprised by what is permitted here:
39. The liturgical color chosen for funerals should express Christian hope but should not be offensive to human grief or sorrow. In the United States, white, violet, or black vestments may be worn at the funeral rites and at other offices and Masses for the dead.
Black, like rose, is a minor liturgical color, and optional at that. This is why it is almost always eliminated from any purchased vestment set. My own sense is that all three colors could be utilized for clergy vestments.
White is most strongly associated with the Paschal Mystery–not only Easter, but Holy Thursday. The question for some parishes would be a plain white or an Easter white. My counsel would be toward the plain.
Violet has other associations in the liturgical year, of course. It may be the third-best of the monochrome choices here.
Any good vestments used in your parishes? Feel free to post links in the combox.
