[vtkusers] Iso-surface coloring

[frency v]

Hello everyone
i have an 3D image (.raw) that  has  values from 0 to 500.
I use vtkcontourfilter to see the image on the renderwindow. But what i want is different color for voxels ie for voxels with value 0 to 100 should have a different color when they appear on tthe renderwindow, and different color for voxels with value 110 to 250 and different color for voxles with value 250 to 500 when they appear on tthe renderwindow.
