Apparently it is possible to define a custom folderpath for Colorbooks in the Revit.ini settings file. (Which can be used for deployment of office standard Revit Settings.)
You can define a custom folderpath for Colorbooks under the [Directories] section in the following format:
ColorbooksLocation=[FILE LOCATION]
So it would be good if this information can be added to the relevant support pages for R24, R25 and future versions; as well as to the downloadable Excel file which explains all possible settings to be configured for a Revit.ini file.
