As long as "specific color" means "font-lock-type-face", then yes.  Set
one or both of the variables called c-font-lock-extra-types,
c++-font-lock-extra-types to a regexp to recognise the type.  Something
like this (untestested):

   (setq c-font-lock-extra-types
    (concat "\_<"
     (regexp-opt '("CFSomethingRef" "kCFFooConstant") t)
     "\_>"))

should do the trick.  It's documented on page "Font Locking
Preliminaries" of the (new) CC Mode manual.
