What are the colours in a Mark Master Mason's apron?

The apron of a Mark Master Mason is trimmed with a two-inch ribbon of light blue edged with crimson, and features rosettes in the same light blue and crimson shades, as set out by the Grand Lodge of Mark Master Masons. Across the degree as a whole, the overall identifying colours of the Order are given by the Grand Lodge of Mark Master Masons as dark blue and crimson.

In earlier literature, Arthur Edward Waite recorded that the distinguishing colours of the degree for both ordinary members and Grand Officers were identical to those of the Craft 1.
