You can override the GTK theme that Zrythm uses along with
much of the color scheme in a special CSS file. It is
a good idea to start by copying the theme from your Zrythm
the installation path on Windows or the Application contents
You should create a file called
theme.css under the
themes directory in your Zrythm directory. For example,
if your Zrythm directory is
/home/me/zrythm, you should
create a file at
The Zrythm theme inherits from the Matcha GTK theme, so additional CSS rules may need to be overridden.
Inside the theme file, you will find lots of colors defined
@define-color. You can override these with your
own colors and Zrythm will use them where possible.
