There's a discussion about that here:
http://groups.google.com/group/grasshopper3d/browse_thread/thread/506c0b5c8cd37df1/
What i gather from that thread is that grasshopper geometry doesen't
store any attributes, but if you know the GUID of the original
referenced geometry, you can extract it by:
Dim obj As IRhinoObject = doc.LookupObject(obj_id)
color = obj.Attributes().m_color
In that thread, that took place in February, David said that
extracting the GUID of referenced geometry would be possible in the
'next release', so it should be available now.
