The Colorado state flag is probably one of the simplest designs off all the state flags in use today. It is however also probably one of the most striking. Officially adopted on June the 5th 1911, Colorado’s flag comprises of three alternate stripes horizontally. The two outer stripes are blue whilst the inner stripe is white. At 1/5th the length of the flag from the staff end lays the letter C in red. A gold colored circle fills the C.


Hidden in the simplicity is a plethora of meaning in the Colorado state flag. This meaning may not be obvious to those looking at it, but it does contain and represent environmental features of the state. The gold circle represents the abundant sunshine that is enjoyed by Colorado’s residents and the blue symbolizes the clear blue skies. The white is for the snowcapped mountains and the red is the color of much of the state’s soil.

At the time the Colorado state flag was designed and adopted it was stipulated that the flag should have an attached cord of gold and silver intertwined with gold and silver tassels. These were to represent the two metals mined in the state, of course gold and silver.


People are surprised to learn that the simple and contemporary design of the Colorado state flag was designed in 1911. It is thought that its style would be more associated with a later date when contemporary became popular and more common. Obviously its designer Andrew Carlisle Johnson was ahead of his time.

It would therefore not be surprising that the Colorado state flag was revised in both 1929 and 1964 when controversy arose over the shades of red and blue used. It is quite clear they must have finally gotten it right when they made the changes because in 2001 a survey rated the Colorado state 16th in popularity!
