[Paraview] Get color on color bar

Tue Mar 22 17:20:43 EDT 2016

Mesa versions 10.5.4 and earlier have a bug that causes issues with VTK. We
recommend upgrading to version 10.5.5 or later. That would be my first
guess. If that is the case we probably need to add something to watch for
that in VTK.

Thanks

Ken
