3d printing gets funny and difficult when you try to do mechanical movement in one-step printed object. Besides if you split the model in two colors the results will improve but also complexity will do because when there is two colors on same surface(for example emoji face) to avoid mixing colors you have to put holes(eyes and mouth) in model color that has not to be printed.
