Featured Listing Colors

How do I change the mouse over color (default light yellow) of the Featured Listings job.
I have editted the CSS to:

ul.job_listings li.job_listing {
font-size: 16px;
}
.rp4wp-related-job_listing>ul li.job_listing.job_position_featured a, .rp4wp-related-job_listing>ul li.no_job_listings_found.job_position_featured a, ul.job_listings li.job_listing.job_position_featured a, ul.job_listings li.no_job_listings_found.job_position_featured a {
background-color: #FFFFFF;
}

This show it white until moused over – how do I edit the mouse over color?
In View Source it show the color associated to: background-color but I edited this and no change?
