If you want to change the color of the highlight can inject the CSS code below:

.form-line-active input:focus {

border : 1px solid red !important;

outline-color : red !important;

}

In addition to that, we would appreciate it if you could provide your form ID. At that time, we can assist more properly. If this does not resolve the issue, please let us know and we will be glad to take another look.
