Is there an option to change the color of the sale text on sale products (currently green)?
While there’s currently no way to do that specifically, the need to have it in a different way is well understood. We plan to add a new option for it in a future update, but until then, you can use the following bit of custom CSS to change its color. You can paste the following bit in Appearance > Customize > Additional CSS.
span.onsale {
background: #000000;
}
