Harlowe change background color for each passage

I have tried this in the past but to no avail, is there a way to change the background color for each twine page/passage. I know you can use th (background:) macro, http://twine2.neocities.org/#macro_background, but this works by basically highlighting the text inside the square brackets instead of the whole page.

Is there a way to do it with tags and CSS, or is it easier than that?
