[vtkusers] Iso band coloring

[David Doria]

If you run this:

http://www.vtk.org/Wiki/VTK/Examples/PolyData/PolyDataIsoLines

On this input: http://rpi.edu/~doriad/VTK_List/Isobands/eight.vtp

The output looks like this:

The contour edges (white lines) are correct, but the coloring is not
what I am looking for. It starts out red, and moves to blue too
quickly - it seems like since the bands are equally spaced, the colors
should continue to be equally spaced across the entire object. Can
anyone see what I am doing wrong?

Thanks,

David
