Articles don't have a bakcground color, they are inside of a main container div that surrounds all of the center columns; which is controlled in template.css under:
background: #ffffff url("../images/s5_white_area.jpg") repeat-x scroll left top;
However, that's going to change the background of the majority of the site. If you need just the articles that will require custom programming - we do not provide modification services like this.
