Claudio, ParaView ignores the LOOKUP_TABLE you specified in your VTK file. Instead, elaborating on what Alan suggested, you can do the following:
* Load your data * Add a "Tensor Glyph" filter. * Color the "Tensor Glyph" filter by the "sample_scalars" array. This should actually happen by default. * Open up the Color Map Editor. * Near the top of the Color Map Editor dialog, check the box "Interpret Values as Categories" * Under "Annotations", click on the toolbutton "Add active values from selected sources". This will assign a unique color to each glyph. You can customize these colors by clicking on the circular color swatch in the left column of the Annotations table.
