By default, Kentico already assigns a CSS class to the control's parent in error. See the sample markup:

  <label class="EditingFormLabel" for="txtText">First name:</label>
  <div class="EditingFormControlNestedControl editing-form-control-nested-control Error">
    <input name="txtText" type="text" maxlength="200" class="form-control">
  <span class="EditingFormErrorLabel">Please enter a value.</span>

So there should be no need to create a javascript function to do this. Simply add this style:div.Error input { background-color: red; }

Right now, I don't believe this is available OOTB, so you might have to write some JS for this.
