title: Wordpress custom page attribute
body: <p>I'm working on a custom WP theme that displays all "pages" as sections in a one page layout.</p>
  
  <p>What I would like to do is add a color chooser to the page designer, so that the user can choose a color to be the background color of that section. </p>
  
  <p>I'm totally new to wordpress so I don't even know what files or functions to look at to add this behavior. </p>
  
  <p>Is there perhaps a prebuilt plugin to do something like this?</p>
