CSS Color?

The website https://s4nr.com/kierandemo/ is using the Toivo Lite, I am trying to change the visited links and the top menu text color to black, where it says Home, Tune In, Schedule, Profiles and Chat it is purple but I would like this pink. I have loaded up the CSS to change this but I cannot see how. Can anyone help?

Thanks
