Hello,
Please try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.
.swatch-on-single {
border: 2px solid grey;
padding: 10px;
}
.wd-swatch.swatch-on-single.text-only.swatch-size-default.active-swatch.swatch-enabled {
background-color: aqua;
}
.swatch-on-single.swatch-enabled:hover {
background: red;
}
.wd-swatch:hover:after, .wd-swatch.active-swatch:after {
opacity: 0;
}
If the code does not work, insert the site admin access into the Private content below the message area.
Best Regards
