It's not absolutely different.  It approximates the X colors where
that is possible.  I did say the behavior should be the same "as much
as possible", didn't I?

Aha, and what would your "system defaults" do when the background mode
changes?  The Windows "default" region color is a very deep blue
background, which will be almost invisible on a dark background.

Yeah, right.
