Bootstrap: Change Background Color Dropdown menu

Question

At the moment i am using this template: http://getbootstrap.com/examples/navbar-fixed-top/

Is there any way to give the background in the dropdownmenu (The one that pops up, when the navbar collapses) another color than the navbar itself?

What i tried so far is this, without success:

.navbar-default .navbar-nav .open .dropdown-menu > .active > a,
.navbar-default .navbar-nav .open .dropdown-menu > .active > a:hover,
.navbar-default .navbar-nav .open .dropdown-menu > .active > a:focus {
    color: #555555;
    background-color: #e7e7e7;
}

Answer 1

Use this

.navbar-nav > li > .dropdown-menu { background-color: #FF0000; }

Answer 2

To get the background color of Bootstrap Navigation Menu dropdowns

.navbar-nav > li > .dropdown-menu a:link,
.navbar-nav > li > .dropdown-menu a:hover { background-color: #FF0000;}
