Colorado is a 1940 American Western film directed by Joseph Kane and starring Roy Rogers.

During the American Civil War a Confederate officer who is also a Captain in the Union Cavalry is keeping Federal troops in the Colorado Territory from reinforcing their armies in the East by forming an alliance of secessionists, outlaws, and opportunists as well as arming hostile Indians.

Donald escapes arrest but confronts his alliance that they are getting rich whilst he is doing all the work and facing all the danger.

Donald takes over by shooting a corrupt Indian Affairs commissioner after informing him that the agent is no longer an asset but a liability.
