On November 15, 2021, the Colorado Supreme Court approved the state legislative redistricting plans approved by the state's Independent Legislative Redistricting Commission on October 11 and 12, 2021.[11] These maps took effect for Colorado’s 2022 state legislative elections.

How does redistricting in Colorado work? On November 6, 2018, Colorado voters approved two constitutional amendments, Amendment Y and Amendment Z, establishing separate non-politician commissions for congressional and state legislative redistricting. Each commission consists of four members belonging to the state's largest political party, four members belonging to the state's second-largest party, and four members belonging to no party. Commission members are appointed by a panel of three judges selected by the Chief Justice of the Colorado Supreme Court. The amendment requires at least eight of the commission's 12 members, including at least two members not belonging to any political party, to approve a map.

The Colorado Constitution requires that state legislative district boundaries "be contiguous, and that they be as compact as possible based on their total perimeter." In addition, "to the extent possible, districts must also preserve the integrity of counties, cities, towns and–where doing so does not conflict with other goals–communities of interest." There are no similar requirements for congressional districts (Source: Ballotpedia)
