Thanks for the tip. What you are suggesting is basically doing manual 
color-mapping, right? I.e. manually iterating over the polydata points, 
using the associated biological cell ID to set the point color (using a 
LUT) in a new separate color array, which then gets displayed. 
Interesting, hadn't thought of that option.

Regards,
Paul
