drop down navigation - roll over effects

I am working on my navigation, but I can not find anything for 'Roll-over' changes on text in drop down.
You will see my navigation roll over is white to red, but it is not on the drop down, I would like the text on the drop down to turn red when mouse rolls over it like the rest of the navigation. But I can not find this option / is it and option? Please help. SIte: http://www.printingcyprus.com/
