Could VTK be used to re-construct colorful 3D using colorful CT images?

In my code, there isn’t such a property.
the objects defined in my code are:

vtkSmartPointer<vtkMarchingCubes> skinExtractor = vtkSmartPointer<vtkMarchingCubes>::New();
vtkSmartPointer<vtkStripper> skinStripper = vtkSmartPointer<vtkStripper>::New();
vtkSmartPointer<vtkPolyDataMapper> skinMapper = vtkSmartPointer<vtkPolyDataMapper>::New();
vtkSmartPointer<vtkActor> skin = vtkSmartPointer<vtkActor>::New();

Which should have this property?
