This tutorial will help you to replace magento default ‘Shop by’ section with Color Swatch block. All attribute options that have swatch image assigned will be displayed as swatches and rest will keep default view. To use Color Swatch swatches in ‘Shop by’ section you will need to create several files and edit few of them. You will need access to magento installation, with permission to copy/edit files and create folders. Before you edit or overwrite any file please create backup copy of it.
