Hi Kostas,
Thanks for reaching out to us. The issue has been resolved. Now, hovering over a color attribute will change the variation images. I’ve made some adjustments to the swatches settings in the special attributes tab (https://prnt.sc/vsBeJURuj-GF)
Please check your website and let us know.
Thank you.
