## ColorPicker

ColorPicker es un selector de color que soporta varios formatos de color.

### Uso básico

:::demo ColorPicker requiere una variable de tipo `string` para ser enlazada a `v-model`.
```html
<div class="block">
  <span class="demonstration">Especifica valor por defecto</span>
  <el-color-picker v-model="color1"></el-color-picker>
</div>
<div class="block">
  <span class="demonstration">No especifica valor por defecto</span>
  <el-color-picker v-model="color2"></el-color-picker>
</div>

<script>
  export default {
    data() {
      return {
        color1: '#409EFF',
        color2: null
      }
    }
  };
</script>
<!--
<setup>

  import { defineComponent, ref } from 'vue';

  export default defineComponent({
    setup() {
      const color1 = ref('#409EFF');
      const color2 = ref(null);
      return {
        color1,
        color2,
      };
    },
  });

</setup>
-->
```

### Alpha

:::demo ColorPicker soporta selección de canales alpha. Para activarlo sólo agregue el atributo `show-alpha`.
```html
<el-color-picker v-model="color" show-alpha></el-color-picker>

<script>
  export default {
    data() {
      return {
        color: 'rgba(19, 206, 102, 0.8)'
      }
    }
  };
</script>
<!--
<setup>

  import { defineComponent, ref } from 'vue';

  export default defineComponent({
    setup() {
      const color = ref('rgba(19, 206, 102, 0.8)');
      return {
        color,
      };
    },
  });

</setup>
