Colorado

flag of Colorado
The Centennial State
Admitted August 1, 1876

Colorado’s original state flag was adopted in 1907, but only one was ever produced and it was never flown publicly.

In 1910, not knowing the state adopted a flag at all, a Colorado chapter of the Daughters of the American Revolution called for submissions for a flag design. The winning submission was designed by Andrew Carlisle Carson.

This (second) flag was officially adopted June 5, 1911.

Its colors were standardized in 1929 and its proportions in 1964.

Composition

The Colorado flag is a triband of blue and white.

A red letter ‘C’ is charged upon the stripes and within the ‘C’ is a golden disc.

Construction

The Colorado flag is produced with a proportion of 2:3.

Colorado statute specifies the proportion and spacing for the flag’s visual elements, which is rendered here.

Attached to the flag should be a cord of intertwined gold and silver, with one tassel of gold and one of silver.
