I was emailed on how to do to this. Here's untested pseudocode by Michael on a good approach. The code won't work exactly out of the box, but it gives you a start point. Post the working code back, please :)

1. Create a new variable that returns the section in your PHP.
2. Use the $section variable to set a class over the entire page
3. Use differently-named classes in your CSS file to change images, colours, etc.

---------------
PHP:

protected function Section($currentPage) {
if($currentPage->ParentID == 0) {
return $currentPage->URLSegment;
} else {
return $this->Section(DataObject::get_one("Page", "`SiteTree`.ID = $currentPage->ParentID AND ShowInMenus = 1"));
}
}

--------------------------------
2. Add variable to template

<html ... >
<body class="section$Section">
<h1>$Title</h1>
<div class="typography">
$Content
</div>
</html>

--------------------------------
3. In your CSS, do

.sectionHome h1 { background-image: url( homepage.jpg) }
.sectionHome .typography { color: blue };

.sectionAboutus h1 { background-image: url( aboutus.jpg) }
.sectionAboutus.typography { color: green };

.sectionServices h1 { background-image: url( services.jpg) }
.sectionServices .typography { color: pink };

Hi,

Here is the part to find the page if it at the top level.
-----------------------------------------------------------------
In newpage.php

<?php
/**
* Defines the NewPage page type
*/

class NewPage extends Page {
static $db = array(
);
static $has_one = array(
);

}

class NewPage_Controller extends Page_Controller {

protected function WhatPage()
{
$page_id1 = $this->ParentID;
if($page_id1 == 0) {
   $filename = $this->URLSegment;
   return $filename;
   }
}
}
?>

In the .ss template

   <head>
      <% base_tag %>
      <link rel="stylesheet" type="text/css" href="tutorial/css/layout.css" />
      <link rel="stylesheet" type="text/css" href="tutorial/css/typography.css" />
      <link rel="stylesheet" type="text/css" href="tutorial/css/form.css" />
   </head>
   <body>
      <div id="Main" align="center">
         <div id="header$WhatPage">
            <div id="Content" class="typography" align="left">
               $Content
               $Form
            </div>
         </div>
      </div>
   </body>

In the CSS file
#headeraccessories {
background-image: url(/jpgimages/<image>.jpg);
background-position:center;
background-repeat:no-repeat;
height: 1079px;
top:0px;
}

-------------------------------------------------------------
This works like a charm for the pages in the top level.

Still working on the code for children pages, so far I have:

else {
   $sitetreeid=$this->ParentID;
   $filename= DataObject::get_one("SiteTree","ParentID=$sitetreeid");
$filename1=$filename->URLSegment;
   return $filename1;
}

But this returns the base pagename of NewPage, not the Top Level page name. I'm still working on it, but if anyone has any ideas, that would be great.

Here's the final code

   protected function WhatPage($currentPage)
   {
      if (!$currentPage) {
         $page_id1 = $this->ParentID;
      }
      else
      {
         $page_id1 = $currentPage->ParentID;
      }

      if($page_id1 == 0) {
         $filename = $this->URLSegment;
         return $filename;
      }
      else {
         $sitetreeid=$this->ParentID;         
         $test1= DataObject::get_by_id("Page","$sitetreeid");
         $pageid2 = $test1->ParentID;
         if ($pageid2 ==0) {
            $filename = $test1->URLSegment;
            return $filename;
         }
         else {
            $test3= $test1->URLSegment;
            return $this->WhatPage($test3);         
         }
      }
   }
