Manager posts don’t have a special color persé, they only have a special color if they are the author of the source
These are the rules when you are logged in backend+frontend at once:
Webuser identity > Manager identity
Webuser Permissions < Manager Permissions
all comments by managers are registered with a positive integer referring to the manager id and all comments by websusers are registered as negative integers.
userid = 1, is a manager user with id 1
userid = -1, is a webuser with id 1
