## Color 色彩

Element 为了避免视觉传达差异，使用一套特定的调色板来规定颜色，为你所搭建的产品提供一致的外观视觉感受。

### 主色

Element 主要品牌颜色是鲜艳、友好的蓝色。

<el-row :gutter="12">
  <el-col :span="6">
    <div class="demo-color-box bg-blue">Blue<div class="value">#409EFF</div></div>
  </el-col>
</el-row>

### 辅助色

除了主色外的场景色，需要在不同的场景中使用（例如危险色表示危险的操作）。

<el-row :gutter="12">
  <el-col :span="6">
    <div class="demo-color-box bg-success">Success<div class="value">#67C23A</div></div>
  </el-col>
  <el-col :span="6">
    <div class="demo-color-box bg-warning">Warning<div class="value">#EB9E05</div></div>
  </el-col>
  <el-col :span="6">
    <div class="demo-color-box bg-danger">Danger<div class="value">#FA5555</div></div>
  </el-col>
  <el-col :span="6">
    <div class="demo-color-box bg-info">Info<div class="value">#878D99</div></div>
  </el-col>
</el-row>

### 中性色

中性色用于文本、背景和边框颜色。通过运用不同的中性色，来表现层次结构。

<el-row :gutter="12">
  <el-col :span="6">
