From most controlled to least controlled, what is the correct order of types of territorial rule over imperialized lands?

A colony is governed directly by the imperial power, so it represents the most control. A protectorate usually keeps some local government but is controlled in important matters, such as foreign relations. A sphere of influence involves less direct control, often limiting another power’s access or influence in a region; therefore the order is colony, protectorate, sphere of influence.
