That's what I do, with a standalone minibuffer frame. And the colors are
different for isearch and for recursive minibuffer levels. The changes are
slight, but noticeable.

With buffer-local background colors (after the release), we could do
something like this for a minibuffer window (not just a frame).

Changing background color this way should be optional, of course.
