Ubuntu – Dark GTK theme for Ubuntu 16.04 (Unity)


I have tried to apply dark themes from Ubuntu 14.04 on 16.04 and they do not come out entirely as expected (different colours and such). What native dark themes for Ubuntu 16.04 are out there? I would prefer a theme retaining the default Unity decorations and icons and simply tweaking colours, but other suggestions are welcome.

Arc Theme Dark

This seems to be a popular theme, albeit somewhat different from the original Unity. This theme also prefers cold colours producing an overall calming and comfortable desktop.

Update: After using this theme for a couple of weeks I must say this is the best I ever had with Unity. The choice and combination of colours is spot on, a serene and beautiful theme. Highly recommended.

This theme can be installed from the Nooblabs PPA:

sudo add-apt-repository ppa:noobslab/themes
sudo apt-get update
sudo apt-get install arc-theme

There is also an Arc icons theme, check more details at the NoobsLab webpage.

Adapta Dark

This theme introduces a number of modifications to window decorations and icons, but the end result is quite crisp. All the colours seem to have been well worked out, producing a nice desktop in different monitors.

enter image description here


sudo apt-add-repository ppa:tista/adapta -y
sudo apt-get update
sudo apt-get install adapta-gtk-theme

It might require some tweaking to get activated, check the details here or follow the steps below.

Install unity-tweak-tool to apply the newly installed theme using:

sudo apt-get install unity-tweak-tool

Now navigate to unity-tweak-tool > Appearance > Theme to choose theme.
