I'm trying to change the header background color on the graphite theme to white, I changed it in the css .ow_top
{
border-bottom: 1px solid #999;
    position: relative;
    height: 135px; /** OW_Control type:text, key:headerHeight, section:1. General Settings, label: Page header height **/

    background-color: #ffff;
}

.ow_header{
  
    background-color: #ffff;
 
}

that didn't work, so I made the ow_themes/graphite/images/top-bg.png white and ftp'd it up overwriting the old one but still the gray background color appears. anyone know how to change that?  http://lilycreek.net/iheart/
