Hi Christoph,
Thanks for reaching out to us. Please try the below CSS at Appearance > Customize > Additional CSS
li.variable-item.no-stock {
box-shadow: 0 0 0 1px red !important; /*Add color here*/
}
Then let me know if it helps or not.
Thank You

Christoph Sauerborn
Hi there,
I would like to change border-color for out of stock items but cannot find any options nor can I find any reference in frontend CSS. Can you please help?
Thanks.
