html - md-select 箭头颜色变化

Question

我能以某种方式更改 vue.js 中 md-select 的箭头颜色吗？

<md-input-container class="wid blueColor">
    <label>Aggregate</label>
    <md-select v-model="aggregate" class="blueColor">
      <md-option value="QUARTER_HOUR">15 min</md-option>
      <md-option value="HALF_HOUR">30 min</md-option>
      <md-option value="HOUR">1 hour</md-option>
      <md-option value="DAY">1 day</md-option>
    </md-select>
</md-input-container>
