Archbishop Hart of Melbourne quoted "Say The Black, Do The Red" in a recent address to the Council of Priests of the Archdiocese of Melbourne.
Faithfulness on the other hand requires that because of the strong connection between liturgy, faith and doctrine, we celebrate the liturgy according to the liturgical books and their General Instructions without variations, except in cases which the books provide. The general rule of “say the black and do the red” with clarity and fervour obtains within these parameters.

Card. DiNardo used the phrase in an interview with ZENIT:
With regard to the liturgy, I think we can take a cue from the liturgical piety of the Church Fathers. In the Fathers, you see an emphasis not only on the words said at Mass, but also the importance of the gestures of the liturgy. In other words, say the black, do the red.
