el-progress实现进度条颜色不同

实现效果：

实现代码如下：

<template>
  <div>
    <h1>进度条排名</h1>
    <div style="width: 400px; height: 40px; margin: 0 auto; display: flex; align-item: center; justify-content: flex-start" v-for="(item, index) in egList" :key="index">
      <div style="width: 15%; line-height: 40px; text-algin: center; padding-left:10px">{{ index+1 }}</div>
      <div style="width: 65%; text-algin: left; font-size: 8px;">
        <!-- 名称 -->
        <div style="height: 20px;">{{item.name}}</div>
        <el-progress :percentage="item.num/1000*100" :show-text="false" :stroke-width="8" :color="getColor(index)"></el-progress>
      </div>
      <div style="width: 20%; line-height: 40px; padding-right: 10px; min-width: 40px">{{Number(item.num).toFixed(2)}}</div>
    </div>
  </div>
</template>
<script>

      egList: [

        },
