The right/easy way to go is to remove your TextProperty ivar from your code 
and just get or set the vtkTextProperty of your TextActor through your API.

You should have no pb with the change above.
As far as priority is concerned, if the color of a vtkTextActor's 
vtkTextProperty has not been changed, its default value is -1.0, -1.0, 
-1.0, which means that the vtkActor2D (i.e. vtkTextActor) color should be 
used instead (to maintain backward comp for a while).
