A fork of the Materia GTK theme.

Important information: Google announced that, from September 2026, Android devices will require ALL apps to be signed by Google, effectively leading to an iOS situation.

Summary

  • Do not edit the CSS directly, edit the source SCSS files and run ./parse-sass.sh

  • To be able to use the latest/adequate version of Sass, install sassc

  • To change the SVG assets color, use a text editor instead of a image editor

How to tweak the theme

Like the upstream Adwaita, this theme is written and processed in Sass.

You can read about Sass at http://sass-lang.com/documentation/. Once you make your changes to the SCSS files, run the ./parse-sass.sh script to rebuild the CSS files.

Here's a rundown of thesupporting stylesheets:

  • _variables.scss

variables to allow easier definition of widget sizing/styling.

  • _color-palette.scss

material design color palette definitions. We don't recommend editing this unless Google updates the color scheme.

  • _colors.scss

global color definitions. We keep the number of defined colors to a necessary minimum. It covers both the light variant and the dark variant.

  • _colors-public.scss

SCSS colors exported through gtk to allow for 3rd party apps color mixing.

  • _drawing.scss

drawing helper mixings/functions to allow easier definition of widget drawing under specific context.

  • _common.scss

actual definitions of style for each widget. This is where you are likely to add/remove your changes.

  • _apps.scss or _extensions.scss

app/extension specific stylings.

How to change the assets color

To keep it maintainable, SVG files are basically edited on text-based.

So if you just want to change the SVG assets color, we recommend using a text editor instead of Inkscape. However, please note that Inkscape is required to render the PNG assets from the SVG files.

Here's an example to change the _accent color_:

  1. Open the following SVG files with a text editor.

- ./src/gtk-2.0/assets.svg - ./src/gtk-2.0/assets-dark.svg - ./src/gtk-3.0/gtk-common/assets.svg - ./src/gnome-shell/3.18/assets/checkbox.svg - ./src/gnome-shell/3.18/assets/more-results.svg - ./src/gnome-shell/3.18/assets/toggle-on.svg - ./src/gnome-shell/3.18/assets-dark/checkbox.svg - ./src/gnome-shell/3.18/assets-dark/more-results.svg - ./src/gnome-shell/3.18/assets-dark/toggle-on.svg

  1. Search #FF4081 (default accent color) and replace with your favorite color.

> The recommended color palette is: https://material.io/guidelines/style/color.html#color-color-palette

  1. Run ./render-assets.sh to render the PNG assets for gtk2 and gtk3.

> Note: inkscape and optipng must be installed to run the script.
