Hi Tom,
It is possible. It does require a little bit more work. I am just back
from a week offline, struggling to catch up with other mail, so I'll just
give you a pointer, and hopefully you'll be able to adapt the example to
your problem.
The main idea is to add the 2 scalar values to your data source, use one
to apply the tube filter, and use the second one to apply the surface
module, thereby giving it the color. This idea of using multiple scalars
is explained on the atomic_orbital example, with a different set of
filters and modules:

Hopefuly, this will sort you out.
Cheers,
Ga�l
