[Paraview] Using a programmable filter to apply custom rgb colors to a ExodusII data set

[Mark Messner]

Hello,

I'm trying to use a programmable filter to apply colors to an ExodusII data
set.  What I'd like to do is to use some of the cell data arrays to
calculate the rgb colors I want to apply, and then insert them into the
data set for display.

I found a partial answer (maybe?) in the mailing list archives
