    (clim 1.1, allegro 4.1)

    We recently borrowed an interior decorator to decorate our windows.
    He decided, for color screens, that the window background should
    be clim:+royal-blue+ and the window foreground should be clim:+white+.

    I have discovered that these two inks are identical ("white") on a B&W Sun
    OpenWindows display.  This makes it rather difficult to use the program.

    The colors are specified as the :stream-foreground and :stream-background
    :panes options to define-application-frame.  These options are evaluated
    at compile time as far as I can tell, which is obviously too early for
    me to examine the characteristics of the stream or the display and
    then select an appropriate ink.

    I suppose clim:make-contrasting-inks was invented to solve this
    problem.  But it does not do as good of a job as our decorator
    in choosing snazzy colors.

    Does clim 1 have a way around this problem?

Couldn't you initialize the foreground and background inks in an
initialize-instance :after method?
