CSS - 将下拉箭头更改为unicode三角形

Question

我已经定制了我的<select>使用方式:

background-color:#ececec;
border:0;
border:1px solid #e3e3e3;
border-radius:3px;
width:100%;
font-family:'FuturaStdLightOblique', sans-serif;
font-size:16px;
color:#616263;
outline:none;
height: 40px;

但我也希望将我的下拉箭头改为符合此设计的外观.我想使用unicode三角形▼(▼)作为向下箭头的替代方法,如果可能的话,将其设置为与我的select标签中的文本相同的颜色.

关于如何在不使用CSS/HTML之外的任何事情的情况下实现这一目标的任何想法？提前致谢.

可能是吧？

*,
*:before,
*:after {
  box-sizing: border-box;
}

* {
  padding: 0;
  margin: 0;
}

form {
  padding: 1rem;
  max-width: 400px;
  margin: 1em auto;
}

.select {
  height: 40px;
  width: 100%;
  overflow: hidden;
  position: relative;
  border-radius: 3px;
  margin-bottom: 1em;
}

.select:after {
  content: "?";
  padding: 12px 8px;
  position: absolute;
  right: 10px;
  top: 0;
  z-index: 1;
  text-align: center;
  width: 10%;
  height: 100%;
  pointer-events: none;
}

.select__field {
  height: 40px;
  width: 100%;
  padding: 5px 15px;
  color: #616263;
  background-color: #ececec;
  border: 1px solid #e3e3e3;
  outline: none;
  font-size: 16px;
  -webkit-appearance: none;
  /* for webkit browsers */
  -moz-appearance: none;
  /* for firefox */
  appearance: none;
  /* for modern browsers */
}


/* remove default caret for ie */

.select__field::-ms-expand {
  display: none;
}

.select__field:focus:invalid {
  border-color: #FD6347;
}

.select__field:required:valid {
  border-color: #006400;
}

.btn-submit {
  color: #fff;
  display: block;
  padding: 15px;
  text-transform: uppercase;
  background: #535C69;
  width: 100%;
  border: none;
  border-radius: 3px;
}

<form action="#" method="post">
  <div class="select">
    <select name="nameValueSelect" class="select__field" required>
      <option value="" selected>Choose option ...</option>
      <option>Option 1</option>
      <option>Option 2</option>
      <option>Option 3</option>
      <option>Option 4</option>
      <option>Option 5</option>
      <option>Option 6</option>
    </select>
  </div>

  <button type="submit" class="btn-submit">Submit</button>
</form>
