After placing a space object and entering a compartmentation functionality, the color fill doesn't work.

Solution: When working with IFCs, opening objects are not room bounding even though the link itself is made Room bounding. This means that it's necessary to use Space separator lines to enclose the spaces. These objects can not send information to the rooms in the ArchiCAD file yet but can be used to send an IFC / DWG with the correct requirements.
