Easily Create Your Own Numix Based GTK Themes With Oomox

Easily Create Your Own Numix Based GTK Themes With Oomox


Oomox is a tool used to generate color variations of the popular Numix GTK 2/3 theme.

Oomox

The tool features built-in presets, but it also allows changing theme colors individually, and it can even generate random themes. The themes generated using Oomox support GTK3, GTK2 and include Openbox and Xfwm4 themes.

Also, the latest Oomox 0.15, released a few days ago, includes initial support for Unity. Whats not included yet is the ability to change the Unity theme image colors and as a result, the window buttons color used by themes generated using Oomox wont change in Unity (so the default Numix color will be used for this).

Note that Numix theme requires GTK 3.16 or newer, so the themes generated with Oomox require the same version.

As far as Ubuntu is concerned, Ubuntu GNOME, Xubuntu, Ubuntu MATE, Lubuntu and Ubuntu (with Unity) are supported. Since it requires GTK 3.16 or newer, than means you need to be using an Ubuntu 15.10 or 16.04 flavor for the themes to work.

An easier way to change theme colors would be GTK Theme Preferences but unfortunately, this tool no longer works with some themes. For instance, in Ubuntu 16.04, GTK Theme Preferences can change both GTK2 and GTK3 theme colors for Ambiance and Radiance themes, but it doesnt work with the Numix GTK3 theme.

Here are a few more screenshots featuring themes generated using Oomox:

Download and use Oomox


Update: Oomox is now available in the main WebUpd8 PPA, for Ubuntu 16.04 and 15.10 / Linux Mint 18. To add the PPA and install the tool, use the following commands:
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt update
sudo apt install oomox
If you dont want to add the PPA, you can download the deb from HERE. Or see the manual installation instructions below.

Arch Linux users can install Oomox via AUR.

1. Install the required dependencies

Oomox requires python3-gobject as well as the following executables: glib-compile-schemas, gdk-pixbuf-pixdata and sass, while Numix theme requires the Murrine GTK2 engine. xorg-xrdb and xmllint are optional.

Install them in Ubuntu 15.10 or 16.04 using the following command:
sudo apt install python3-gi libglib2.0-bin libgdk-pixbuf2.0-dev ruby-sass libxml2-utils x11-xserver-utils gir1.2-gtk-3.0 gir1.2-glib-2.0 gtk2-engines-murrine

2. Download and install Oomox

You can download Oomox from HERE.

To download Oomox and install it into /opt/oomox/, you can use the following commands:
sudo apt install wget
cd /tmp
wget https://github.com/actionless/oomox/archive/0.16.1.tar.gz
tar -xvf 0.16.1.tar.gz
sudo mkdir /opt/oomox
sudo cp -r oomox-0.16.1/* /opt/oomox/

Thats it.

To run the Oomox GUI, use the following command:
/opt/oomox/gui.sh

Using Oomox is very simple - select the preset you want to use (and optionally change the colors if you want to make your own custom Numix theme) and click "Export theme":


After the theme is generated, it should be available in the ~/.themes folder. You can use a tool like Unity Tweak Tool, GNOME Tweak Tool and so on to change the theme.

Report any bugs related to the generated themes to the Oomox GitHub page. If you think the bugs are Numix theme-related, report them to the Numix GTK Theme GitHub page.
