Schake,
take a look at color-theme-retro-green. It works for me, setting
everything to green on black.

I'm pasting the code, from colortheme.el, below. You can see you don't
need to list every face. Also check the orange theme, which is made
from the retro-greeen. You can make a retro-white just the same :)


(defun color-theme-retro-green (&optional color func)
  "Plain green on black faces for those longing for the good old
days."
  (interactive)
  ;; Build a list of faces without parameters
  (let ((old-faces (face-list))
        (faces)
        (face)
        (foreground (or color "green")))
    (dolist (face old-faces)
      (cond ((memq face '(bold bold-italic))
             (add-to-list 'faces `(,face (( t (:bold t))))))
            ((memq face '(italic underline show-paren-mismatch-face))
             (add-to-list 'faces `(,face (( t (:underline t))))))
            ((memq face '(modeline modeline-buffer-id modeline-mousable
                          modeline-mousable-minor-mode highlight region
                          secondary-selection show-paren-match-face))
             (add-to-list 'faces `(,face (( t (:foreground "black"
                                               :background ,foreground
                                               :inverse t))))))
            (t
             (add-to-list 'faces `(,face (( t (nil))))))))
    (color-theme-install
     (append
      (list (or func 'color-theme-retro-green)
            (list (cons 'foreground-color foreground)
                  (cons 'background-color "black")
                  (cons 'mouse-color foreground)
                  (cons 'cursor-color foreground)
                  (cons 'border-color foreground)
                  (cons 'background-mode 'dark)))
      faces))))

(defun color-theme-retro-orange ()
  "Plain orange on black faces for those longing for the good old
days."
  (interactive)
  (color-theme-retro-green "orange" 'color-theme-retro-orange))
