I think this way it is much cleaner:


(make-face 'font-lock-number-face)
(set-face-foreground 'font-lock-number-face "DodgerBlue4")
(setq font-lock-number-face 'font-lock-number-face)

(setq number-mode-list '(c-mode-hook
                         c++-mode-hook
                         lisp-mode-hook
                         emacs-lisp-mode-hook
                         python-mode-hook
                         cperl-mode-hook))

(dolist (mode number-mode-list)
  (add-hook mode
            '(lambda ()
              (font-lock-add-keywords nil
               '(("\\<\\([0-9]+\\([eE][+-]?[0-9]*\\)?\\|0[xX][0-9a-fA-
F]+\\)\\>" .
                  font-lock-number-face))))))
