Can i adjust the Social Wall 'roll-over' effect on images from transparent dark grey to 85-90% transparent variation of #C082BD

To resolve this issue, you can add the following code to the Header Code ( Dashboard > Customize > Custom Code):

<style>
.block .view-pic .mask, .block .view-product .mask { background-color: rgba(192, 130, 189, 0.8); }
.block .view-pic:hover .mask, .block .view-product:hover .mask { opacity: 1; }
</style>

Hope this helps !
