Well, as I see in Adobe products when Labels have been implemented in
DK, only one color can be assigned to an image, and i think it's
enough, else representation in GUI will become a rainbow.

In digiKam 8.0.0, there is a profile for the metadata sharing with
other photo management applications. The settings can be exported and
imported in digiKam through the metadata advanced setup panel.
DarkTable is supported as a profile. Look online documentation here :


Other profiles can be created if you use another application (such as
Photostation, Acdsee, LR, etc..). Just set up the advanced metadata
for your needs, and export the settings to a profile file. We can add
this file (INI text based) to digiKam as well. Just share the file in
a bug report...
