Change Color Wordpress Theme Template - Graphene Theme

You can create a Wordpress Child Theme by following the instructions and then install the text below into a style.css file and place it in your template directory >Public HTML>Directory Folder>wp-content>themes.  After the css file is uploaded, you just need to update your theme in Wordpress.  The child folder will be at the same level as your main theme.  Then you can pick two colors from your main page to create the gradient in the Graphene theme.
