Custom style - how to change the colour of "Open Buddy List"

[Darat]

I've a custom style installed and it works fine apart from the "Open Buddy List" link in the Quick Links drop down menu in the Navbar.

The text appears white as it does in the standard vBulletin, not the colour of the menu options (see attached screen grabs) but the rollover colour is correct.

I presume this is because the colour for that is set different to the standard menu items? If so where do I find it to alter it?
