Composite Semaphore Flag for the Letter Y - Yankee

The Composite Semaphore Flag for Yankee has a blue background, because Y is the 25th letter of the alphabet.  Reason being, 5 is coded to blue and the ones digit value of a letter sets the colour.  As a reminder blue is the fifth colour of the spectrum.  Also the stars represent the right-starboard arm of the Semaphore Signaler.
