The Colorado Constitution, according to Article XIX, can be changed via these routes:
- A constitutional convention. The Colorado General Assembly by a two-thirds vote of each chamber (the Colorado House of Representatives and the Colorado State Senate) can place a measure on the ballot asking the state's voters if they want a constitutional convention. The voters can approve a constitutional convention with a simple majority vote. Any proposed amendments coming out of such a convention are then to be submitted to a statewide vote of the people who can approve them by a simple majority.
- Through a legislatively-referred constitutional amendment.
- Either chamber of the general assembly can propose an amendment.
- Two-thirds of each chamber must vote affirmatively for the proposed amendment in order for it to go on the statewide ballot for potential voter ratification.
- Ratification occurs through simple majority vote.
- Elections on legislatively-referred constitutional amendments must take place on the same days that general elections are held for members of the Colorado General Assembly.
- No one general assembly is allowed to propose amendments to more than six of the Colorado Constitution's 29 articles.

Constitutional convention - how called
The general assembly may at any time by a vote of two-thirds of the members elected to each house, recommend to the electors of the state, to vote at the next general election for or against a convention to revise, alter and amend this constitution; and if a majority of those voting on the question shall declare in favor of such convention, the general assembly shall, at its next session, provide for the calling thereof. The number of members of the convention shall be twice that of the senate and they shall be elected in the same manner, at the same places, and in the same districts. The general assembly shall, in the act calling the convention, designate the day, hour and place of its meeting; fix the pay of its members and officers, and provide for the payment of the same, together with the necessary expenses of the convention. Before proceeding, the members shall take an oath to support the constitution of the United States, and of the state of Colorado, and to faithfully discharge their duties as members of the convention. The qualifications of members shall be the same as of members of the senate; and vacancies occurring shall be filled in the manner provided for filling vacancies in the general assembly. Said convention shall meet within three months after such election and prepare such revisions, alterations or amendments to the constitution as may be deemed necessary; which shall be submitted to the electors for their ratification or rejection at an election appointed by the convention for that purpose, not less than two nor more than six months after adjournment thereof; and unless so submitted and approved by a majority of the electors voting at the election, no such revision, alteration or amendment shall take effect.
| Text of Section 2:
Amendments to constitution - how adopted
(1) Any amendment or amendments to this constitution may be proposed in either house of the general assembly, and, if the same shall be voted for by two-thirds of all the members elected to each house, such proposed amendment or amendments, together with the ayes and noes of each house thereon, shall be entered in full on their respective journals. The proposed amendment or amendments shall be published with the laws of that session of the general assembly. At the next general election for members of the general assembly, the said amendment or amendments shall be submitted to the registered electors of the state for their approval or rejection, and such as are approved by a majority of those voting thereon shall become part of this constitution.
(2) If more than one amendment be submitted at any general election, each of said amendments shall be voted upon separately and votes thereon cast shall be separately counted the same as though but one amendment was submitted; but each general assembly shall have no power to propose amendments to more than six articles of this constitution.
(3) No measure proposing an amendment or amendments to this constitution shall be submitted by the general assembly to the registered electors of the state containing more than one subject, which shall be clearly expressed in its title; but if any subject shall be embraced in any measure which shall not be expressed in the title, such measure shall be void only as to so much thereof as shall not be so expressed.
