如何在select2上更改项目的文本颜色

<select class="custom-select2">
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
  <option value="3">Option 3</option>
</select>

.custom-select2 .select2-selection__rendered {
  color: red; /* 设置文本颜色为红色 */
}

<link rel="stylesheet" href="path/to/select2.css">
<script src="path/to/select2.js"></script>

$(document).ready(function() {
  $('.custom-select2').select2();
});
