## Color 色彩

Element Plus 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 Plus 主要品牌颜色是鲜艳、友好的蓝色。

<el-row :gutter="12">
  <el-col :span="10" :xs="{span: 12}">
    <div class="demo-color-box" :style="{ background: primary }">Brand Color
      <div class="value">#409EFF</div>
      <div class="bg-color-sub" :style="{ background: tintColor(primary, 0.9) }">
        <div
          class="bg-blue-sub-item"
          v-for="(item, key) in Array(8)"
          :key="key"
          :style="{ background: tintColor(primary, (key + 1) / 10) }"
        ></div>
      </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）。

<color-box />

### 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" :xs="{span: 12}">
    <text-box :text-colors="textColors" />
  </el-col>
  <el-col :span="6" :xs="{span: 12}">
    <border-box :border-colors="borderColors" />
  </el-col>
  <el-col :span="6" :xs="{span: 12}">
    <div class="demo-color-box-group">
      <div
      class="demo-color-box demo-color-box-other"
      :style="{ background: black }"
      >基础黑色<div class="value">{{black}}</div></div>
      <div
      class="demo-color-box demo-color-box-other"
      :style="{ background: white, color: '#303133', border: '1px solid #eee' }"
      >基础白色<div class="value">{{white}}</div></div>
      <div class="demo-color-box demo-color-box-other bg-transparent">透明<div class="value">Transparent</div>
      </div>
    </div>
  </el-col>
</el-row>
