Thanks all those who replied, as I was hunting for solutions :)
I have checked and both 'MacOS system highlight' and 'Microsoft Word page color' solutions are valid. However changing page color is not desirable as this value is save in the document and applies only to the Page View. The system option requires Word to restart, which makes initial testing of colors tiresome but is a more coherent use of MacOS features.
More importantly, the highlight color needs to be more visible when in Accessibility high-contrast mode - which is great for distraction free or nighttime writing. Word for Mac 2016 has a Focus Mode but it requires an Office 365 Subscription. Without this, a distraction free, "night mode" can be achieved by setting Word in Fullscreen, hiding its ribbons and using system Accessibility features (Display > Invert + Grayscale + Differentiate + Increase contrast + Display contrast up a notch).
Finding the right highlight color is tricky as text color does not always invert, and Word for Mac appears to overlay a shade of the system highlight color. So when in high-contrast mode a system highlight color that was good for the system was not clear enough in Word, and when it was clear enough for Word it was too strong for the system. For example, "Graphite" (#d8d8dc, ~85% gray) was too light in night-mode. And with "Other..." set to 50% gray, in normal mode this was too dark for the system but ok in Word, and vice versa in night mode. Therefore I would suggest setting the system highlight color to 66% gray, which gives an equal perceptual weight of highlight in both normal and night mode.
All the best,
Mike
As mentioned by Patty, to change MacOS system highlight:

As mentioned by Zedsdea, adjust the highlight in Word by changing the page color:
