Hi Claudio, I have never done this, but it sounds like you are looking for an annotation, rather than a continuous color map. Could you flip to annotations, then color using an int?

I've a list of 8 tensors (here represented as circular ellipsoids, see short vtk file below) I typically open the file and filter using ("tensor glyph"). Now I would like to assign to each tensor glyph a unique color specified by an rgba sequence (e.g. 0.1 0.3 0.2 1) How can I do that? I tried to append a scalar lookup table followed by a rgba one but without success Thanks -Claudio # vtk DataFile Version 3.0 Random data to test tensors ASCII DATASET UNSTRUCTURED_GRID POINTS 8 float 0 0 0 1 0 0 0 1 0 1 1 0 0 0 1 1 0 1 0 1 1 1 1 1 POINT_DATA 8 TENSORS spherical_ellipsoid float 1 0 0 0 1 0 0 0 1 1 0 0 0 1 0 0 0 1 1 0 0 0 1 0 0 0 1 1 0 0 0 1 0 0 0 1 1 0 0 0 1 0 0 0 1 1 0 0 0 1 0 0 0 1 1 0 0 0 1 0 0 0 1 1 0 0 0 1 0 0 0 1 SCALARS sample_scalars float 1 LOOKUP_TABLE rgbtable 0 1 2 3 4 5 6 7 LOOKUP_TABLE rgbtable 8 0.2 0.4 0.3 1.0 04.0 2.0 1.0 1.0 0.4 1.0 0.2 1.0 1.0 1.0 0.7 1.0 0.2 0.0 5.0 1.0 1.0 0.2 1.0 1.0 2.0 1.0 1.0 1.0 0.0 1.0 0.9 1.0
