i can′t change the color of my rss feed header font

When changing color of my widget area i can change the backround and my font text for 3 links but not for the RSS feeds

h3, .widget > h1 {
	color: #fff;
	text-align: center;
	background-color: #DC241F;
	font-size: 14px;
	font-weight: bold;
	text-transform: uppercase;
	border-bottom: 2px solid #fff;
	padding-bottom: 2px;

im using the toolbox theme for it. i been trying to read up on what to do and tryed adding

.widget_rss .widget-title a{
  color:#FF0000;
}

To my style.css but can′t get it to work. anyone got any idea of how i could do this?
