What is this highlighted border for focused radioitem and how to change this?

I used CSS to create color boxshadow like this:
.custom-control-input:focus ~ .custom-control-label::before {

-webkit-box-shadow: 0px 0px 0px 2px #192A6D;

-moz-box-shadow: 0px 0px 0px 2px #192A6D;

box-shadow: 0px 0px 0px 2px #192A6D;

}

but under boxshadow there is still this light orange color visible.

I can not easily change color of focused input.
