[vtkusers] vtkActor.GetProperty()->SetColor() not working for me

[Mike Gagnon]

Hi list,

I'm making the following call after having added an actor to my view.  
Is it possible to change the color after an actor is added? My call to 
SetColor has no effect:

pActor->GetProperty()->SetColor(1, 0.75, 0);   // yellowish color

Thanks,
Mike
