Thanks to @Aravisian suggestions and tips in this topic I managed to create a custom version of ZorinBlue-Dark theme with the following features:
- Icons are borrowed from ZorinBlue-Dark
- GTK 3.0 CSS styling is borrowed from ZorinGrey-Dark theme but I made colors a bit brighter than the original theme.
- The GNOME shell theme is borrowed from ZorinGrey-Dark theme but I made colors a bit brighter than the original theme.
- The beautiful blue gradient color used in ZorinBlue-Light is used.
Here is the GitHub repository of my theme:
Here are the preview images of this custom theme:
