Background color

I would like to change the background color of the menus and toolbars from white to something a bit more off-white so I can see the contrast better. I’ve played around with Tools > Options but can’t find anything that allows me to do this.

I work on computers that have Linux Mint (Rebecca) and Windows 7.

Thanks in advance,
C

Most likely the Personalization can help you. Tools > Options > LibreOffice > Personalization > choose your own theme or pre-installed other themes.
