Thanks for all your clarification.

Finally I found where to customize: Customize Group: flyspell, and then 
I found the flyspell-duplicate/incorrect options. Now my custom.el 
(after a few tries) is:

$ cat custom.el
[...]
(custom-set-faces
 ;; custom-set-faces was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 '(flyspell-duplicate ((t (:foreground "Gold3" :underline t :weight 
bold))))
 '(flyspell-incorrect ((t (:foreground "Red1" :underline t :weight 
bold)))))

Thanks,
Angelo.
