Still not worked, my code is

--------------
(copy-face 'default 'my-red-face)
(set-face-foreground 'my-red-face "red")
(copy-face 'default 'my-blue-face)
(set-face-foreground 'my-blue-face "blue")

(defun gnus-user-format-function-a (header)
   "Test dynamic color"
   (let  ((date-time (format-time-string "%m/%d" (safe-date-to-time
(mail-header-date header)))))
      (if (string= date-time (format-time-string "%m/%d"))
         (propertize date-time 'face 'my-red-face 'mouse-face 'my-blue-
face)
         (propertize date-time 'face 'my-blue-face 'mouse-face 'my-red-
face))))

(setq gnus-summary-line-format "%U%R%z %ua: %1{%B%-23,23n%} %s\n")
-------------

It seems that gnus will modify the face property of the text
returned,  but not the mouse-face property.
