Black. The entries for the users or user groups to whom application-level permissions have been granted are shown in black. If you are an administrator with the site-level permission Manage Apps or if you have been granted the application-level permission Manage User Permissions for this app, you can determine which permissions other users may have for the app. For example, you can define that a user can only edit the metadata of the app, or that a user may only view and download statistics. A check box is provided for these users and user groups so that you can remove all application-level permissions for these users, if required.

Grey. The entries for the users to whom the site-level permission Manage Apps has been granted are shown in grey. You cannot remove any application-level permissions for these users. Therefore, a check box is not shown for such a user.
