The Colorado State FlagThe flag was designed by Andrew Carlisle Johnson in 1911 and adopted by the state of Colorado that year. However, the Colorado State legislature did not specify the size of the "C" on the flag or the exact shade of blue or red that the flag should contain. This is why some early Colorado flags were produced with slightly different colors and some even had the "C" for Colorado completely within the center stripe. On February 28, 1929, the Colorado State General Assembly added to the description of the Colorado State flag that the blue and red would be the same color as the flag of the United States. On March 31, 1964, the Colorado State legislature further dictated the diameter of the gold disc to be equal to the center stripe in the Colorado State Flag.
