I asked it, but it turned out to be impossible. According to their
explanation,
- PDF file produced by pdflatex doesn't specify the foreground color
  explicitly. preview-latex sets up the Ghostscript initialization
  to specify the default foreground color, so the text in the resultant
  png image is rendered with that color.
- However, PDF file produced by xelatex does specify black as the
  foreground color explicitly. Thus the initial default color isn't used
  at rendering the png image.

I'll add notification in preview-latex documentation that the preview
images don't follow the foreground color of emacs when xelatex is used.
