One way to do the above could be as follows:
in the DBASE process, clone (pfClone) the original pfScene part
where you want to modify, let's say colour
perform the changes in the cloned portion
bufferDelete the original part from the pfScene
bufferAdd/bufferMerge the cloned porion to the scene graph
hope this helps
