I've recently installed a dark theme for Ubuntu (16.04) and it's great but the only problem I have is that I can't see the icons in LibreOffice. I've tried the default icon themes in LibreOffice but they're all the same. This is what it looks like:

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.
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.
Installation:
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.

To get the oxygen theme:
After a few tries I've found that oxygen icon theme works great with the dark theme I have currently installed (and will probably look good with others as well). You can select the theme from the window (Tools -> Options) in the screenshot (click to see it bigger). Here's how it looks now:
Another one that works great is
libreoffice-style-elementary.Sifr is not bad if you prefer monochrome.
That can be made whiter as indicated here.
