It depends on how long you stay in Colorado. You are a domilciliary resident of Texas. That is where your main home is. However, if you reside more than 6 months in the home that you have in Colorado, you are considered a statutory resident of Colorado. Here's a link to a Colorado publication that has more information on this:
Income 6: Part-Year Resident and Nonresident ... - Colorado.govWhat about if you lived and worked in Colorado but you begin working in Texas later in the year and are in the process of moving?
Q. What about if you lived and worked in Colorado but you begin working in Texas later in the year and are in the process of moving?
A. You are still a CO resident until you establish a permanent residence in TX. Permanent residence is when your whole family arrives in TX, to stay. You will file a part year resident return for CO, including the TX income that was received while you were still a CO resident.
