Crystalline, with its Color Chooser, effectively has an infinite number of possible color / style combinations which can easily be setup in seconds. However, the template is still bundled with 12 prebuilt configurations to show off the true potential of the theme before you start configuring yourself.
You can edit the combinations in the administrator as outlined on the Style Control page.
Below is a preview / screenshot of each style variation. Please click on the image to load a live example of each style variation.
