One quirk of Microsoft Word is that for historical reasons it has highlighting, which only allows a small number of specific colors, but also equivalent functionality in background shading for characters which allows arbitrary colors. IIRC, because this doesn't really make sense, libreoffice just has highlighting which allows arbitrary colors, but it can be confusing because it may by necessity become background shading when you export as a word file. Unfortunately, the UI for background shading is absolutely terrible in Word (there are different types of border/shading settings and you have to open the menu but then select the correct type to even see the current settings that are being applied) so people who don't know about it will be unlikely to figure out where it is or how to change it.
