Hi @davidyannick
Pane background color is DRKBASE in the .hcs file
Path bar is probably PathGadgetGradHi and PathGadgetGradLow
The timeline was one of the DopeSheet entries I believe
Network editor background color is GraphBackground, which is found in the .inc files.
The wire color should be GraphWire, again in the .inc file. Confusingly, the VOP graph wires are set in the .hcs files.
Hope that helps
