Text color .ajax__tab_body

I am trying to set the text color using the following css but can't find the color or foreground color property...

.MyTabStyle .ajax__tab_body
        {
            font-family: verdana,tahoma,helvetica;
            font-size: 10pt;
            background-color: #fff;
            border-top-width: 0;
            border: solid 1px #d7d7d7;
            border-top-color: #ffffff;
        }
