Why my emacs can't change color?

[Hongzheng Wang]

Hi, my emacs has a problem, ie, it can't change color.
Hereis a part of my .emacs:

(setq default-frame-alist
      '(
        (vertical-scroll-bars . right)
        (top . 35) (left . 40)
        (width . 80) (height . 35)
        (cursor-color . "Orchid")
        (cursor-type . box)
        (foreground-color . "Wheat")
        (background-color . "DarkSlateGray")
        (font . "-adobe-courier-medium-r-normal-*-*-140-*-*-m-*-iso8859-1")
        )
      )

This dot emacs file works correctly under redhat linux, but
failed under debian.

My emacs's version is:

"GNU Emacs 21.2.1 (i386-debian-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2002-03-23 on raven, modified by Debian"

I don't know what's the matter.

Thank you for your help!
