Morse Code Flag for the Letter X - X-Ray : _ . . _
The Morse Code Flag for the letter X has two stripes and two stars. The order is reflective of the specific code for X which is related to DOTS and DASHES. Since Morse Code Flags are always read downwards, it clearly spells out DASH, DOT, DOT, DASH, which is the letter X in Morse Code.
The flag has a green background because the letter X is the 24th letter of the alphabet. The number 4 is coded to green, because, green is the 4th colour of the rainbow/spectrum. Yellow is included because yellow is the contrast minority-indicator for a green background/field. Also note that the tens place value for twenty-four is ignored. Only the ones place value is used to set the main colour of the background, which for the letter X is 4, that is coded to green. Thus we have a dominantly green flag for the letter X in Morse Code.
