Help changing text color in drop-down menu

I have installed the Boldy theme and am at the moment modifying its looks. Though I cannot seem to find where to change the color of the drop-down menu’s hover text. Now it is blue and I would like to change it to white. I have been searching everywhere in the style.css file but cannot find where to change the values. I tried adding color: #fff; in different places but with no luck. Any ideas how to solve the problem?
