I need to change the value of an RGB node programmatically. The data path of the node in question is
bpy.data.node_groups["Compositing Nodetree"].nodes["RGB"], as can be seen in the screenshot attached.
However, if I enter that path into the Python console, no node groups are returned. I.e.
bpy.data.node_groups.keys() is empty.
What is going on here? How can one access node groups?
