Create color style options for your site using the Genesis Framework:
In addition to the default color style, the code above will generate a “Color Style” metabox on the Genesis > Theme Settings page in your dashboard.
In that metabox you will see the following options in the dropdown menu: “Default, Blue, Green, Orange and Red.”
If the “Blue” color style option is selected, the .theme-blue body class will be applied and can be used to target CSS that is specific to the blue color style.
