Customised Icons - Devonthink Groups versus Indexed Groups

I have noted if i customised the group folder icon & this in turn is synced to DTTG I get two behaviours;

With a standard DT Group the icon colour is replicated faithfully over to DTTG
With indexed Group the colour of the icon is “subdued” or pastel version of original … is this expected behaviour signalling an indexed item?

No, this has no relationship to files being indexed.

You are using a shallow sync for that database…

Download Files: On demand


Download Files: Always


Actually, the icons of groups that are not set to always download their content but download content on demand appear lighter/pastel.
