Colo. Rev. Stat. § 15-1-803
Fiduciaries have all powers conferred upon them by the provisions of this part 8, unless limited by the language or provisions in the will or trust instrument expressing a clear intention that powers conferred under this part 8 shall be denied to the fiduciary. They have, in addition to the powers conferred in this part 8, such other or further powers as are set forth in the will or trust instrument or as are provided by other statutes or by court rule or order. If any power specifically conferred on a fiduciary by the will or trust instrument conflicts with any power conferred by this part 8, the fiduciary shall be deemed to have only the power specifically conferred by the will or trust instrument and not the conflicting power conferred by this part 8. Provisions in articles 10 to 20 of this title concerning the exercise of powers in the administration of an estate by an executor having powers under a will shall apply to executors having powers conferred under this part 8.
