Reboot? Clean cache?
Maybe some Qt apps do not follow, IDK.
IDK, it works for me
It's all in gitlab
git clone https://gitlab.com/SGSm/make-dragonized-blue.git
cd make-dragonized-blue
./make-dragonized-blue # no sudo !!!
The root privileges are needed to copy/write to the /usr/share/themes/ area and remove root files in ~/
Open System Settings / Appearance / Colors, load /home/.kde4/share/apps/color-schemes/sweet-blue.colors, mark Sweet-blue, click apply, reboot. Have fun
It is now supported everywhere. Thank you so much. I think it was the issue of cache. I did the same thing from start. Changed the theme , cleared the cache and reboot and now it works.
