Perhaps the behavior of the :inverse-video face attribute is what is
confusing.  It uses the swapped foreground and background colors for
actual display.

Application writers can specify the same face attributes on X and on
ttys.  So if :inverse-video was off on X, turn it off on tty too, and
vice versa.

In which NEWS section would you expect to find this fix?

Possible candidates:

* Lisp Changes in Emacs 22.1
** Face changes


* Incompatible Lisp Changes in Emacs 22.1


* Incompatible Editing Changes in Emacs 22.1
