Hi stonedcrystals,

The carousels in our theme are not Revolution Slider carousel so they do not have the same options as Rev. Slider does, the theme has only the simple arrows for now, the color can be changed but the form now and for that we are planning to add them in the upcoming versions of the theme.

You can achieve this manually, by adding the following CSS in your Custom CSS:

.woocommerce .single-product .images .product-images-carousel .nextprev-arrow, .woocommerce .single-product .images .thumbnails .nextprev-arrow {
    background: rgba(0,0,0,.3);
    border-radius: 50%;
    padding: 10px;
}
.woocommerce .product .item-info .price ins, .woocommerce .product .item-info .price > .amount {
    word-break: break-word;
}

You're welcome

Hi there,

Can you try adding this CSS, it should work now since there are some changes WooCommerce made on it's classes since the last update:

.woocommerce .single-product .kalium-woocommerce-product-gallery .main-product-images .nextprev-arrow i, .woocommerce .single-product .kalium-woocommerce-product-gallery .thumbnails .nextprev-arrow i {
    background: rgba(0,0,0,.3);
    border-radius: 50%;
    padding: 10px;
}
