Morse Code Flag for the Letter U - Uniform

The Morse Code Flag for the letter U has a red background, two white stars, and one white stripe.  The stars represent DOTS while the Stripe represents a DASH, in Morse Code.  As these types of flag are always read downwards it reflects the nature of the letter U.  The flag is red, because this colour is coded to the number 1.  As the letter U is the 21st letter of the alphabet, we have a red flag.  Also note the numeral 2 from 21 is ignored, since Morse Code flags only use the ones place value to calibrate the colour.
