A class factory can be a way to hand back the same class with different initialization parameters. The point is to hide the initialization stuff behind a simple call.

In the case you describe here, if the code calling this thing knows which one it wants, I think you should actually either just make the two classes and call them or make a class that has some kind of method like "set_collection_color()" for switching the behavior.
