 - __selector__ String _(default: `'img[data-adaptive-background="1"]'`)_ a CSS selector which denotes which images to grab/process. Ideally, this selector would start with _img_, to ensure we only grab and try to process actual images.
 - __parent__ falsy _(default: `null`)_ a CSS selector which denotes which parent to apply the background color to. By default, the color is applied to the parent one level up the DOM tree.
