Check out this entry in dired-font-lock-keywords:

    ;; Files suffixed with `completion-ignored-extensions'.
    '(eval .
      ;; It is quicker to first find just an extension, then go back to the
      ;; start of that file name.  So we do this complex MATCH-ANCHORED 
form.
      (list (concat "\\(" (regexp-opt completion-ignored-extensions) 
"\\|#\\)$")
	   '(".+" (dired-move-to-filename) nil (0 dired-ignored-face))))


That suggests you could define a new face and add a similar entry to
dired-font-lock-keywords that references it instead of
dired-ignored-face, for the simple regexp "\\.nry\\'".
