If you are on Windows, you should see something printed in the command
window when you press whatever key you want.

The main problem is not the colour, as I know how to change that in an
actor... my question was: from the actor, is there any way I can get
back the vtkSphereSource to change its radius, center and so on? It
looks possible in C++ (as Amy pointed out) but in Python calling
GetSource() always returns None.
