Change color to the highlighter module position

Hi!

I use Joomla installation ver 2.5.1.

I have placed a menu, called News in the Highlighter Module position.
The idea is to have shortlinks to my websites most interesting stuff here.
If I place Menu Items in the Highlighter module position, the text is black.
But when I hoover over a menu Item the text changes to white, and is not possible to see, since the Highlighter module position background is also white.

I wonder if anyone can help me where I can change the CSS code for this, so that the color changes to for example grey if I hoover over the menu Item in the Highligter module position.

Best Regards!
Mattias
