The Customizer add-on allows you to easily change colors of ratings and link buttons using the The WordPress Theme Customizer, it’s very useful to see changes live in the preview page and be able to use custom colors via the color picker.
The add-on adds a new section for the WP Rich Snippets plugin in the Theme Customizer screen page. You can preview color changes while you are on the same screen, without having to edit any line of code.
