[vtkusers] Color lookup table for unstructured grid (XML) file

[Michael Nolde]

Hello,

I'm trying to realize a color lookup table in combination with an unstructured grid (XML) .vtu file. I want to avoid having to define one color over and over for different points.

The lookup table can well exist in an external file (.json or .xml preset), or, preferably, is realized through some XML notation inside the .vtu file.
Is that even possible and, if so, could someone send me an example of an according XML file section?

Thank you very much,
Michael
