gtk3

Generate colour themes for GTK3 applications.

Description​

GTK3 is the older version of the GTK toolkit, still used by many applications like GIMP, Inkscape (older versions), and various legacy GNOME apps. The plugin generates a CSS file that overrides application colours.

Output path​

~/.config/gtk-3.0/tinct-gtk3.css

Usage​

tinct generate -i image -p ~/wallpaper.jpg -o gtk3

Flags​

FlagDefaultDescription
--gtk3.output-dir~/.config/gtk-3.0Output directory for GTK3 theme files

Configuration​

After generation, import the theme in your GTK3 configuration.

Step 1: Import the CSS​

Add this line to ~/.config/gtk-3.0/gtk.css:

@import url("tinct-gtk3.css");

Step 2: Use a compatible theme​

For tinct colours to apply properly, use the adw-gtk3 theme which respects custom colour definitions:

# Arch/CachyOS
sudo pacman -S adw-gtk-theme

# Or install adw-gtk3 on other distributions

Then set in ~/.config/gtk-3.0/settings.ini:

[Settings]
gtk-theme-name=adw-gtk3-dark

Why adw-gtk-theme?​

Standard GTK3 themes have hardcoded colours that override CSS variables. The adw-gtk-theme (also known as adw-gtk3) is designed to respect CSS colour definitions, making it compatible with tinct's generated colours.

Themed elements​

The GTK3 theme affects:

  • Window backgrounds
  • Button colours
  • Selection highlights
  • Text colours
  • Scrollbars
  • Menu colours
