Feature request from paales, posted on GitHub Jun 21, 2016
Currently using 2.1-rc3.
There is no API available for product option swatches. It makes sense if we are able to use the
ProductAttributeOptionManagementInterface to add new swatch texts to products.
Maybe to have better separation of concerns we could have a
ProductAttributeOptionSwatchManagementInterface to add swatch information to an existing option.
