Flag of Colorado
The colors in the Colorado state flag represent environmental features of the state. White symbolizes the snow on her mountains, gold acknowledges the abundant Colorado sunshine, red represents Colorado's red soil, and blue is a symbol of her clear blue skies. Colorado has flown many flags - three countries and eight Territories have laid claim to (and flown their flags over) what is now the state of Colorado.
Today's official Colorado flag consists of three equally sized stripes; the outer stripes are the same color blue as the national flag and separated by the white center stripe. There is a large semi-circular "C" on the flag, which is the same shade of red as the U.S. national flag. In the opening of the letter "C" there is a gold disc.
