(Color) swatches on shop page

I’m looking for a way to add (only) the color swatches to the shop page. I’m working with the Konte Theme that uses your plugin, but only on the product variations on the product page.

I have seen that supro theme added the swatches also to the product page:

Any ideas how to do it?

Thanks and best, Caspar
