Hello,
1) Theme Options > Shop elements > Variation swatches > set different colors for “Swatches border color” and “Hover/active swatches border color”.
2) Add this code in Theme Options > Custom CSS > Custom CSS for desctop:
.archive.woocommerce-page.s_widgets-open-close .sidebar .sidebar-widget:not(.sidebar-slider) .widget-title>span {
font-size: 18px;
}
