Color the "flats" by assigning a different cell scalar to each tetrahedron. 
(Ask the output for the number of cells; create a vtkScalars with that many 
scalar values; assign the vtkScalars to the CellData of the dataset.) Then 
when you use vtkDataSetMapper (or vtkGeoemtryFilter), the faces of the mesh 
will be extracted along with the scalar associated with the tetrahedron, 
and they will be colored differently. You might look at randomCellColors.tcl

A similar approach can be used to color vtkHull.
