Добавление классов в код javascript onhover

Question

В настоящее время у меня на моей странице есть внешний скрипт, который заставляет текст в div «contact» менять цвет в зависимости от того, какой элемент «item» завис. Теперь я знаю sh, что не только div «contact» меняет цвет, но также div меню и div учебной программы, а также любой другой div, который я мог бы добавить позже. Я попытался изменить мой текущий javascript, чтобы сделать это, добавив еще одну переменную let и включив ее в сценарий. Однако до этого момента ничего не получилось. В настоящее время я изучаю свой javascript, чтобы иметь возможность вносить эти изменения. Но, может быть, кто-нибудь подскажет, как это сделать максимально чисто?

let $contact = $('#contact');


$('.item').hover(function() {
  let $target = $($(this).data('target')).toggleClass('hide_default');
  $('#contact').css('color', $target.css('color'));
});

      <br> I love my childhood memories, which were filled with colors, papirs, pencils and handcraft works. I developed an obsession towards various kinds of creative fields: photography, developing analogue photos, architecture, - percieving buildings
      as shapes, volumes and combination of materials, as well as learning to look upon typography as shapes with entrenched characthers. When I realized that graphic design brought together all of these different passions of mine, I pursued it with enthusiasm.

$("#contact, div, span, .whateverClass").css('color', #colorYouWant);
