I do something similar to this for most programming modes:

,----
| (defvar operators-regexp 
|   (regexp-opt '("+" "-" "*" "/" "%" "!"
|                 "&" "^" "~" "|"
|                 "=" "<" ">"
|                 "." "," ";" ":" "?"))
|   "Regexp matching symbols that are operators in most programming
|   languages.")
| 
| (setq operators-font-lock-spec
|       (cons operators-regexp
|             (list 
|              0 ;; use whole match
|              'font-lock-builtin-face
|              'keep ;; OVERRIDE
|              )))
| 
| (font-lock-add-keywords
|  'c++-mode
|  (list 
|   operators-font-lock-spec))
`----

Clearly you can use whatever face you want instead of font-lock-builtin-face.
