Entity status

Colorado is classified here as u.s. state. That label describes the entity represented by the flag and prevents a territory, state or constituent area from being presented as a sovereign country.

Additional flag context

The C stands for the state name, for the Spanish word colorado meaning ruddy or coloured red, and encircles a gold disc for the state's exceptional number of sunny days.

The original 1911 law did not specify the size or position of the C, and it was redrawn twice — in 1929 and 1964 — before the design settled.

It is one of the few US state flags with no lettering and no seal, and consistently ranks among the best-regarded in design surveys.
