Swatcheroo

The Swatcheroo is an app that uses product variants options and automatically replaces them with swatches. You do not need to create new variant options for the app, just edit the style for existing options on your store. You can easily customize all existing options in your store (like Sizes, Materials, Colors) with one click. No programming/coding required: The app installs itself instantly and requires no coding. It works with Shopify themes without any modification from your side.
