Menu Link Font Colour

Hi All,

On our blog which can be seen at http://blog.simonandsimon.co.uk/ you will see a blue menu bar which appears to have no text in it – if you hover towards the far left of the bar however you will see home come up – however it is usually invisible – meaning the font must be the same colour as the menu – however I cannot work out how to change this – have looked at the usual solutions online and it does not seem to work –
example of where someone said it should be editable:

#access ul li.current_page_item > a,
#access ul li.current_page_ancestor > a,
#access ul li.current-menu-ancestor > a,
#access ul li.current-menu-item > a,
#access ul li.current-menu-parent > a {
color: #fff;
}
* html #access ul li.current_page_item a,
* html #access ul li.current_page_ancestor a,
* html #access ul li.current-menu-ancestor a,
* html #access ul li.current-menu-item a,
* html #access ul li.current-menu-parent a,
* html #access ul li a:hover {
color: #fff;

However ours is already fff and so should the text not be white?- is there an individual piece of css code I can put in or anything at all to make the color white?

Thank you for any help!
