PowerPoint 2010 can be used to create an Office theme. That theme then can be used to apply to a SharePoint site. It’s a very easy and flexible way to produce themes for SharePoint Sites. Site Collection admin right is needed to add the theme to the site collection. Then a SharePoint Site Admin can apply the theme to any site within the site collection.

What’s the best way to start creating a new site that does not look like an out of the box SharePoint site?

First start with changing/customizing the Theme. If that’s not enough, customize or create a new Master Page.
Hello Asif,

Once a valid Office Theme is uploaded to the site collection Theme gallery, it should be available throughout the site collection.
