@jayniel,
It’s not possible to change the color of the icons from the controls at the moment but you can always change it through CSS by putting the CSS into your Additional CSS option in Customizer.
For changing Pros Background Color
.wp-pros-cons .pros-content .wppc-box-symbol {
background: green;
}
For Changing Cons Background Color
.wp-pros-cons .cons-content .wppc-box-symbol {
background: red;
}
The color of the list icons are coming from SVG, so you’ve to change it directly from the SVG. Just open the plugin folder and go to assets/icons and open check-solid.svg and then change the fill color to your preferred color, same goes for the cons icon.
Try to do the SVG changes in a child theme as new updates would remove it.
Let me know how it goes.
Thanks.
