List of Colorado state symbols

The U.S. State of Colorado has many adopted symbols and emblems. Most of these symbols and emblems were adopted by acts of the Legislative Assembly of the Territory of Colorado, and after statehood, the General Assembly of the State of Colorado.[1] A few of these symbols were adopted by executive action of the Governor. Federal agencies designated some of these symbols in honor of the state. Each entry explains the manner and date of adoption.
The first insignia of Colorado, the territorial motto: NIL SINE NVMINE,[2] was adopted by the First Session of the Territorial Legislature on November 6, 1861. The seal and coat of arms of the Territory of Colorado were specified by the First Session of the Territorial Legislature but not created until November 11, 1861.[3]

Notes
- ^ The Coat of Arms of the State of Colorado was implicitly defined by the legislation creating the Seal of the Territory of Colorado on November 11, 1861, and the Great Seal of the State of Colorado on March 15, 1877.
- ^ The Colorado state flag was adopted on June 5, 1911. The 1911 legislation that adopted the flag did not stipulate the precise hues of red and blue to be used, and so on February 28, 1929, the General Assembly stipulated that the colors be the same as the colors on the U.S. flag. Controversy arose over the size of the letter 'C,' and on March 31, 1964, the General Assembly further modified the 1911 legislation by revising the distance from the staff for the letter 'C' and its diameter.
- ^ The State of Colorado is nicknamed the Centennial State because to joined the Union on August 1, 1876, four weeks after the centennial of the United States Declaration of Independence.
- ^ The Colorado River did not officially flow through the State of Colorado until July 25, 1921, when President Warren G. Harding signed House Joint Resolution 32 – To change the name of the Grand River in Colorado and Utah to the Colorado River.[38][39][40][41] Prior to this date, the origin of the Colorado River was officially the confluence of the Grand and Green rivers at 38°11′21″N 109°53′09″W / 38.1892°N 109.8857°W in what is now Canyonlands National Park of Utah.
- ^ USS Colorado was named for the Colorado River,[d] and predated the creation of the Territory of Colorado in 1861.
- ^ USS Colorado was renamed USS Pueblo on November 9, 1916 to free up the name for a new battleship to be named USS Colorado.
- ^ On Tuesday, August 1, 1876, U.S. President Ulysses S. Grant certified that the conditions of the Colorado Enabling Act had been fulfilled and issued Proclamation 230 — Admission of Colorado into the Union.[7] The Territory of Colorado became the State of Colorado, the 38th U.S. state, also known as the Centennial State.
- ^ The 2026 Colorado statehood sesquicentennial postage stamp commemorates the 150th anniversary of Colorado statehood.[g] The forever stamp was designed by USPS art director Derry Noyes and features a photograph of 13,826-foot (4,214 m) Jagged Mountain by Colorado nature photographer John Feilder entitled Foggy Jagged Mountain, Weminuche Wilderness.[45] The stamp was unveiled by Amber McReynolds, Chair of the Board of Governors of the United States Postal Service, and Colorado Governor Jared Polis in a ceremony at the History Colorado Center in Denver on Saturday, January 24, 2026.[46]
