The Roman scheme is not the only Christian liturgical colour system in use: Eastern Orthodox practice follows a considerably less standardised approach, with colour conventions varying meaningfully by jurisdiction, Greek, Russian and other national traditions each carrying somewhat different customary associations, and Eastern practice generally places less doctrinal weight on the specific colour worn than Western canon law historically has, treating colour more as accumulated custom than as a fixed, centrally regulated system.
Anglican and some Lutheran practice generally follows the Roman scheme closely, reflecting these traditions' historical continuity with pre Reformation Western liturgical custom, though with some local and denominational variation, including in a small number of traditions the use of blue rather than violet during Advent specifically, a distinction some communities maintain to visually differentiate Advent's hopeful anticipation from Lent's more austerely penitential character, both of which the Roman scheme otherwise marks with the same violet. Rose, a notably rarer colour, appears on two specific days within the Roman calendar, Gaudete Sunday in Advent and Laetare Sunday in Lent, marking a brief, deliberate softening of penitential violet partway through each of these two preparatory seasons, a small exception within the wider system that liturgical tradition reads as a reminder that joy remains present even within a season primarily given to penitence and preparation.
