Hello,

Thank you for your question.

So here are some code snippets that you can add to your Custom CSS section in Theme Settings to change some parameters

1. Background color with opacity

.basel-hover-info .product-element-top {
    background-color: #651919;
}
.basel-hover-info:hover>.product-element-top>a {
    opacity: 0.1;
}

2. Text color

.basel-hover-info .product-title a {
color: #ECC9C9;
}

3. Transition time

.basel-hover-info .product-element-top>a,
.basel-hover-info .quick-view,
.basel-buttons .yith-wcwl-add-to-wishlist,
.basel-hover-info .hover-mask {
    -webkit-transition: all .15s ease-in-out;
    -moz-transition: all .15s ease-in-out;
    -o-transition: all .15s ease-in-out;
    transition: all .15s ease-in-out;
}

Hope this will help you.
