Standard CTB for Sectionsettings

Hallo

I have been setting up our internal standards for BIM and I have not found a standard .ctb file that is a match for the layer colors found in _sectionsettings.dwg.

I Am told its not proovided and we have to create one. Can you pls confrim ?

If so Is there a system / logic with which the layers colors have been assigned in this file ? or is it random and users must create a ctb ?

Im asking because is more than 300 layers and I do not want to cause any damage in case I want to modify them.

Thanks in advance
