   git clone https://github.com/imarkoff/Marble-shell-theme.git
   cd Marble-shell-theme
   

3. Run the program (install all accent colors, light and dark mode):

   python install.py -a
   

   • more vibrant color in active buttons:

     python install.py -a --filled
     

4. After successful file creation open Extensions app, go to User Themes - ··· - Settings.
5. Select the shell theme you want.

Tip

For updating the theme, run the git pull command in the Marble-shell-theme directory and run the program again. If Marble theme is used, updates will be applied automatically.

Tip

If you want to install only one color, use the --red, --yellow, --green, --blue, --purple, --gray option.

Want to install a custom color, group buttons in the panel, use launchpad icon or some other tweaks? See the installation tweaks section for more information.
