How do I change the colour of the body layout?

Here is the site I'm setting up at the moment http://clogs-forwomen.com/ I can't change the colour of the layout without it changing the entire background with it as well.

Also how do I get rid of the page title showing up as a big heading on the page, this happens for each page, as you can see the home page has the title "Home" as a big heading at the top of the page.


Thanks Anyone
