It seems OK to me.

Firstly, you'll need to be using the PostScript back-end,
as filling regions is only supported via PostScript.

Thus you'll need to load Xy-pic using a line such as:


Secondly, you'll need to be processing the LaTeX file
using TeX + dvips + Ghostscript , rather than using pdfTeX.
Your TeX installation should give you a way to do this easily.

Finally, the Xy-pic coding can use the [F*] frame, along with
a color specifier. That is, it would be something like as follows:

$$  %\UsePSframes
  *[F*:gray]\xybox{\xymatrix{ *+[Fo:red]{A} & *+[Fo:thicker]{B} \\ C  
& D }}

The \UsePSframes  should not be necessary. If the coloured frames
and fills don't work, for some reason, then try with
  \UsePSframes  uncommented.

The example above should produce a result as in the attached image.
