I've always used colors to distinguish dom0 windows from other
windows. Colors are much easier to notice are wrong when tired, in a
hurry, etc. The only window which can make grey window titles/borders
on my system is dom0.

I don't see why the GuiVM couldn't also be easily identified in this
manner. Is there another consideration that makes this different than
the case of guivm=dom0 now, other than the case where the GuiVM is not
full screen / owning the display?
