The Colorado State Seal was adapted from the Territorial Seal that was adopted by Joint Resolution of the First Territorial Assembly on November 6, 1861. The statutory provision for the official seal of statehood was provided for by Act of the First General Assembly of the State of Colorado, approved on March 15, 1877.
By statute, the Seal of the State is two and one-half inches in diameter with the following device inscribed: A heraldic shield, the upper portion of which depicts three snowcapped mountains with clouds surrounding them; the lower part consists of a miner's badge, as prescribed by the rules of heraldry; as a crest above the shield, the eye of God with rays proceeding from the lines of a triangle; below the crest, and above the shield, as a scroll, is the Roman "fasces" which is a bundle of sticks with an axe blade projecting, bound by a band imprinted with the words, "Union and Constitution"; below the whole motto, "Nil Sine Numine," which commonly translated means "Nothing Without Providence"; the whole is surrounded by the words, "State of Colorado," and the figures "1876," the year of Colorado's statehood.
The official colors of the seal, fixed by a 1976 Executive Order, are as follows:
Red: The sky behind the mountains, the single band with the word "UNION" and the ring containing the words "STATE OF COLORADO, 1876".
