Main Nav transparent color

How do I make the main navigation have no background color? I was able to do this:

.main_nav {background-color:yellow;}

I want to get rid of the white, and just see the yellow. Here is my site: http://robbycornish.com/wowsite/products/wow-premium-pvc-boxes/ Thanks!

` body .sf-menu li, #primary-nav ul.sf-menu a:focus { background-color: transparent; } `

Thanks, that worked! But I decided to go back to default. Thanks again!
