LibreOffice icons hard to see with dark themes

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:

I've found out that I could just install a new icon theme using the terminal. See the available themes with:

sudo apt install libreoffice-style

You get this:

  libreoffice-style-sifr 1:5.1.6~rc2-0ubuntu1~xenial3
  libreoffice-style-oxygen 1:5.1.6~rc2-0ubuntu1~xenial3
  libreoffice-style-human 1:5.1.6~rc2-0ubuntu1~xenial3
  libreoffice-style-hicontrast 1:5.1.6~rc2-0ubuntu1~xenial3
  libreoffice-style-elementary 1:5.1.6~rc2-0ubuntu1~xenial3
  libreoffice-style-tango 1:5.1.6~rc2-0ubuntu1~xenial3
  libreoffice-style-galaxy 1:5.1.6~rc2-0ubuntu1~xenial3
  libreoffice-style-breeze 1:5.1.6~rc2-0ubuntu1~xenial3
  libreoffice-style-mint 5.1+3

To get the oxygen theme:

sudo apt install libreoffice-style-oxygen

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.
