changing menu color in custom menu

I have added some footer boxes, one of which has a custom menu. I have tried using firebug to locate the correct css to change the colour of the text in the menu and to also take away the underline using the text decoration command.

As of yet I cannot seem to pin it down. Can someone help me fidn the correct info to add to my css. (already have relevant files in a child theme)
