Edit theme

Initial setup
1

I am new with eM Client. I like the Modern theme but I would like to change the color of the left Email bar (where the mail accounts and folders are displayed). 

So I downloaded the Thema.emtheme file and opened in in Notepad. 

But where (on which line number) can I find the setting to change this specific color?

Thanks for your help!

I don’t have much experience but you can look at the section
