I'd like the Navigation bar font to be more bold or brighter?

My site is: http://www.fallsinsurance.com/wp/

I'd like the page titles on the navigation bar (Home, About Us, Contact Us, etc) to not be so...gray. I like the background being gray, but I want the font to be either bolder or white (or both!). I know they turn white when you scroll over them, but I need them to be more visible.

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

#menu li a{
color:red;
font-weight:bolder;
}
#menu li.current_page_item a{
color:red;
}

Inplace of "red" put your color code.

 

Thank you, Gourav!
