Composite Semaphore Flag for the Letter U - Uniform

The Composite Semaphore Flag for Uniform has a red background, because U is the 21st letter of the alphabet.  The background colour is assigned to the ones digit value of the letter, which is one for Uniform.  One is coded to red and white is its assigned contrast indicator.  The stars indicate the right-starboard arm of the Semaphore Signaler.
