View On Instagram Button

Hi,
we can easily handle button color by using CSS.
update the color in below CSS code and paste in the custom CSS

.instagallery-actions .igact-instalink {
    background: #c32a67;
    color: #fff;
    border: 1px solid #db8c40;
}
.instagallery-actions .igact-instalink:hover {
    background: #da894a;
}
