It is possible to create color swatches using the Import tool.

For this purpose, you will need to create a CSV file and put your color swatches data in this file formatting it as described in the section CSV Import: Color Swatches. In the file, you will need to specify a swatch name, position, color, and image for each color swatch you want to add and upload this CSV file via the Catalog -> Import section of the store back end.

To import color swatches using existing global product attributes, you will need to use the basic CSV file format described in CSV import: Classes & Attributes with the field swatches added to the file.

To import color swatches using existing product-specific attributes, you will need to use the basic CSV file format described in CSV import: Product Attribute Values with the field swatch added to the file.
