one-dark/gtk-2.0/README.md

Editing the theme

• The Colors and includes are defined in gtkrc, gtkrc-dark and gtkrc-darker for each theme variant.
• main.rc contains the major part of the theme
• panel.rc contains the panel styling for XFCE and Mate
• apps.rc contains some application specific rules

Because this theme is heavily based on the pixmap engine, a lot of the styling comes from the images in the assets and assets-dark folders. Don't edit these images directly. Instead do the following

• Open the assets.svg or assets-dark.svg file in inkscape. Each object in the .svg file corresponds to an image in the assets and assets-dark folder.

• Find the object you want to edit and make your changes. Important: Don't change the obejct id.

• Save assets.svg or assets-dark.svg and delete the images corresponding to the edited .svg objects from the assets or assets-dark folder (or just delete everything in the assets or assets-dark folder).

• Run ./render-assets.sh or ./render-dark-assets.sh from a terminal.
