Neat idea! More generally, setting a background-color on the region-body
element, and surrounding the content of fo:flow by a block that resets
the background should do the job:
<fo:layout-master-set>
<fo:simple-page-master master-name="page" page-width="21"
page-height="29.7" margin="2cm">
<fo:region-body background-color="yellow"/>
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="page">
<fo:flow flow-name="xsl-region-body">
<fo:block background-color="white">
<!-- here the real content... -->

You’re welcome :-)
