Colo. Rev. Stat. § 13-80-118
If, when a cause of action accrues against a person, the person is out of this state and not subject to service of process or has concealed himself, the period limited for the commencement of the action by any statute of limitations shall not begin to run until he comes into this state or while he is so concealed. If, after the cause of action accrues, he departs from this state and is not subject to service of process or conceals himself, the time of his absence while not subject to service of process or the time of his concealment while not subject to service of process shall not be computed as a part of the period within which the action must be brought.
