The Color Swatches add-on helps users visualize different colors and fabrics by displaying them as clickable swatches on the storefront's product page. It's very convenient for customers to perceive the whole color range when they can see these options. And it's a much better experience rather than a tiresome reading of all options' names, especially when there is plenty of them.
Use the add-on in conjunction with the product attributes and product variants' features, e.g., to display product attributes as swatches. For example, suppose you build variants based on the attributes and add an image for every variant. Then, when a customer selects a color, the product image will change to show the selected color's product.
