One again it is confusing to categorize this... - It is for digikam, but it is meant to make digikam blend in with the GTK+ Adapta Nokto theme :-D

::: Installation :::

1) Download the *.colors file (... really? :-D )


2) Put it in a "colorschemes" folder which digikam knows about.
It can be:

~/.kde/share/apps/color-schemes/
or
~/.local/share/digikam/colorschemes/

The last one is where it is at if you are running Solus. I had to create the folder "colorschemes".


3) Start/Restart digikam and pick Adapta-Nokto-Solid-Flat


Screenshot is from digikam running on Solus Budgie, which is my current setup.


Enjoy!
