Menu Hover Color – Sub-Pages

Hi guys, I have created several sub-pages of a main parent page on my site, I want to change the hover color on the primary menu as it's coming up black, to my chosen color. You previously gave me this code to change the menu which works fine for all parent pages but not sub-pages - can you give me the code to do this now too? /* For menu bar color – hover color */ #header-menu ul.menu li:hover > a, #header-menu ul.menu a:focus { background-color: #647a64; } Thanks!
