Solved it…kinda

If the box-shadow color is not specified in the sonar effect than it will inherit the color of it’s element. read about it here
So, if I go into the shortcodes.css and delete all of the colors from @keyframes sonarEffect the sonar color will inherit the color of the icon!

/*sonar effect*/
@-webkit-keyframes sonarEffect {
	0% {opacity: 0.3;}
	40% {opacity: 0.5;box-shadow: 0 0 0 2px , 0 0 10px 10px , 0 0 0 10px ;}
	100% {box-shadow: 0 0 0 2px , 0 0 10px 10px , 0 0 0 10px ;-webkit-transform: scale(1.5);opacity: 0;}
}
@-moz-keyframes sonarEffect {
	0% {opacity: 0.3;}
	40% {opacity: 0.5;box-shadow: 0 0 0 2px , 0 0 10px 10px , 0 0 0 10px ;}
	100% {box-shadow: 0 0 0 2px , 0 0 10px 10px , 0 0 0 10px ;-moz-transform: scale(1.5);opacity: 0;}
}
@keyframes sonarEffect {
	0% {opacity: 0.3;}
	40% {opacity: 0.5;box-shadow: 0 0 0 2px , 0 0 10px 10px , 0 0 0 10px ;}
	100% {box-shadow: 0 0 0 2px , 0 0 10px 10px , 0 0 0 10px ;transform: scale(1.5);opacity: 0;}
}

The problem is that I went into the parent theme folder to make this change. So, any updates will wipe it out.

I read here that even if I copy ‘shortcodes.css’ into a child theme folder that the child theme may not use it, relying on the parent themes CSS instead.

Any tips?
