Customization

Theming

Personalize your shell with dynamic Material You color schemes and Base16 palettes.

Matugen

This shell utilizes Matugen for system-wide theming. It automatically generates harmonious Material You color palettes directly from your wallpapers, allowing you to customize the shell, GTK applications, and other compatible software seamlessly.

Theme Storage

Your custom or generated JSON theme files are saved in your local configuration directory:

Path
~/.config/caffyne-shell/themes/

Base16 Theme Machine

We've made it effortless to create custom themes from over 300 established Base16 color palettes. Simply drop your YAML file into our JSON generator for Matugen and load the generated themes directly into your configuration folder.

Theme Machine

Generate Matugen-compatible JSON themes instantly from over 300 Base16 color palettes.

Base16 Palettes

Browse the official Tinted theming repository for hundreds of ready-to-use Base16 color palettes.

Light Mode currently relies on the "dark" variables. If needed, swap the "dark" and "light" blocks within your generated JSON file.

Fonts

Regular Font

Regular fonts manage the interface text across the shell. While you can use a GUI interface like gnome-tweaks, you can also set it instantly via gsettings in your terminal.

We recommend setting the GTK Font Size to 10.5pt (14px) for optimal readability and perfectly centered labels.

Via CLI (e.g. Inter):

gsettings set org.gnome.desktop.interface font-name 'Inter 10.5'

Your custom font files (.ttf / .otf) should be placed in your local font directory:

Path
~/.local/share/fonts/

Monospace Font

Monospae fonts are utilized by terminals and code editors but can also be selected in "Theming"for the caffyne shell interface. You can configure your system-wide monospace font using fontconfig.

Create or edit your local font configuration file:

Path
~/.config/fontconfig/fonts.conf

Insert the following configuration to set your preferred monospace typeface (e.g., Kode Mono):

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <alias>
        <family>monospace</family>
        <prefer>
            <family>Kode Mono</family>
        </prefer>
    </alias>
</fontconfig>
After saving the file, remember to rebuild your font cache by running fc-cache -fv in your terminal.
