I have only done this for the vtkDistanceWidget, but the
vtkAngleWidget should work similar,
and the code-segment is in C# (and ActiViz.NET), so some conversions
might be needed ;-)

   vtkDistanceWidget distWidGet = new vtkDistanceWidget();
   /* init, ... DistanceWidget  */
   //get 2D representation
   vtkDistanceRepresentation2D rep2D =
   	(vtkDistanceRepresentation2D)distWidGet.GetRepresentation();
   vtkPropCollection propies = new vtkPropCollection();
   rep2D.GetAxis().GetActors2D(propies);
   //propies.GetItemAsObject(0) |-> vtkAxisActor2D
   if (propies.GetItemAsObject(0) is vtkAxisActor2D)
   {
      vtkAxisActor2D ax =
      	(vtkAxisActor2D) propies.GetItemAsObject(0);
      ax.GetProperty().SetColor(0, 0, 0); //black
   }
