	Well, using the [Help][Customize...] menu item to set the faces
works, sorta.  Even this is bad, because I change colors on the fly.  In
my .emacs, I have:

(if (eq window-system 'x)
  (progn 
    (defun white () (interactive)
      (set-mouse-color "green2")
      (set-cursor-color "red")
      (set-foreground-color "black")
      (set-background-color "antiquewhite")
      (set-face-background 'region "cyan3" (selected-frame))
      (set-face-foreground 'region "black" (selected-frame))
      (set-face-foreground 'modeline "yellow" (selected-frame) )
      (set-face-background 'modeline "black" (selected-frame) )
    )

    (defun blue () (interactive) 
      (set-mouse-color "cyan3")
      (set-cursor-color "cyan3")
      (set-foreground-color "cyan3")
      (set-background-color "darkslateblue")
      (set-face-background 'region "LightGoldenrod4" (selected-frame))
      (set-face-foreground 'region "cyan3" (selected-frame))
      (set-face-foreground 'modeline "darkslateblue" (selected-frame) )
      (set-face-background 'modeline "cyan3" (selected-frame) )
    )

    (defun green () (interactive)
      (set-mouse-color "green")
      (set-cursor-color "cyan3")
      (set-foreground-color "yellow")
      (set-background-color "dark green")
      (set-face-background 'region "grey" (selected-frame))
      (set-face-foreground 'region "black" (selected-frame))
      (set-face-foreground 'modeline "white" (selected-frame) )
      (set-face-background 'modeline "black" (selected-frame) )
    )

    (defun black () (interactive)
      (set-mouse-color "green")
      (set-cursor-color "firebrick3")
      (set-foreground-color "sky blue")
      (set-background-color "black")
      (set-face-background 'region "grey" (selected-frame))
      (set-face-foreground 'region "black" (selected-frame))
      (set-face-foreground 'modeline "white" (selected-frame) )
      (set-face-background 'modeline "black" (selected-frame) )
    )

    (defun red () (interactive)
      (set-mouse-color "black")
      (set-cursor-color "black")
      (set-foreground-color "red")
      (set-background-color "grey80")
      (set-face-background 'region "grey" (selected-frame))
      (set-face-foreground 'region "black" (selected-frame))
      (set-face-foreground 'modeline "white" (selected-frame) )
      (set-face-background 'modeline "black" (selected-frame) )
    )

    (black)
    (set-default-font "*-courier-medium-r-*-*-12-*-*-*-m*")

    (menu-bar-mode 1)			; turn it back on 
    (defvar color-menu (make-sparse-keymap "Colors"))
    (define-key global-map [menu-bar Color] (cons "Color" color-menu))
    (define-key color-menu [white] '("White" . white))
    (define-key color-menu [blue]  '("Blue"  . blue))
    (define-key color-menu [green] '("Green" . green))
    (define-key color-menu [black] '("Black" . black))
    (define-key color-menu [red]   '("Red"   . red))
))

	This lets me change colors to suit my mood.  What can I put in
the defuns to change gnus colors appropriately?  (And, in a non-gnus
emacs question, how can I set one of the color schemes and the font as
the default for all frames, not just the first one?)
