Changing the background Color

Hi ,
Try adding following css in your 'custom-style.css' file which is there in 'zeropoint/_custom' directory.

#top_bg {
  background: #663333 none repeat scroll 0 0;
}

#body_right, #body_left {
  background: #CC6633 none repeat scroll 0 0;
}

#top_right, #top_left {
  background: none;
}

#body_bg, .eopage {
  background: #000 none repeat scroll 0 0; 
}

/*Css to change the font color*/
a, a:link, .title, .title a, .node .terms, #aggregator .news-item .categories, #aggregator .source, #aggregator .age, #forum td .name, div.admin-panel .description {
  color: #330000;
}

Please clear cached data here- /admin/settings/performance .
Please change the color values according to your need
