Composite Semaphore Flag for the Letter Z - Zulu

The Composite Semaphore Flag for Zulu has an indigo background, because Z is the 26th letter of the alphabet.  Reason being, 6 is coded to indigo and the ones digit value of a letter sets the colour.  As a reminder indigo (navy blue) is the sixth colour of the spectrum.  Also the stars represent the right-starboard arm of the Semaphore Signaler.
