layui.use(function(){
  var colorpicker = layui.colorpicker;
  var layer = layui.layer;

  // 渲染
  colorpicker.render({ // eg1
    elem: '#ID-colorpicker-demo-1', // 绑定元素
    change: function(color){ // 颜色改变的回调

    </div>
  </div>
</form>

<!-- import layui --> 
<script>
layui.use(function(){
  var colorpicker = layui.colorpicker;
  var $ = layui.$;

  // 渲染
  colorpicker.render({
    elem: '#ID-colorpicker-demo-form',
    color: '#1c97f5',

    color: 'rgb(68,66,66)',
    format: 'rgb' // 默认为 hex
  }); 
  colorpicker.render({ // eg2
    elem: '#ID-colorpicker-demo-rgba',
    color: 'rgba(68,66,66,0.5)',
    format: 'rgb',
    alpha: true // 开启透明度滑块
  });
});
</script>

    alpha: true, // 开启透明度
    format: 'rgb'
  });
  colorpicker.render({ // eg2

    color: 'rgb(0,150,136,0.6)', // rgba
    alpha: true,

  // 渲染
  colorpicker.render({ // eg1
    elem: '#ID-colorpicker-demo-predefine-1',
    color: '#c71585',
    predefine: true // 开启预定义颜色
  });
  colorpicker.render({ // eg2
    elem: '#ID-colorpicker-demo-predefine-2',
    color: '#9d8a0e',
    predefine: true, // 开启预定义颜色

<hr>
<div id="ID-colorpicker-demo-all"></div> 
<span style="padding-left: 6px;">演示：选择颜色并确定，改变上方按钮背景色</span>

<!-- import layui --> 
<script>
layui.use(function(){

  var layer = layui.layer;
  var $ = layui.$;

  // 渲染
  colorpicker.render({
    elem: '#ID-colorpicker-demo-all',
    color: '#16baaa',
    predefine: true,
    alpha: true,
    done: function(color){
      layer.msg('选择的值：'+ color); // 选择完毕的颜色值
      
      // 清空或取消选择时也执行 change
      color || this.change(color); 
    },
    change: function(color){
      // 给当前页面头部和左侧设置主题色
      $('#ID-colorpicker-demo-all-btn').css('background-color', color);
    },
    cancel: function(color){ // 取消颜色选择的回调 --- 2.8+
      this.change(color);
    }
  });
});
</script>
  

颜色框尺寸

  <div id="ID-colorpicker-demo-size-lg"></div>

layui.use(function(){
  var colorpicker = layui.colorpicker;

  // 渲染
  colorpicker.render({

    size: 'lg' // 大号下拉框
  });
  colorpicker.render({
    elem: '#ID-colorpicker-demo-size-sm'
    //,size: 'sm' // 默认 sm
  });
  colorpicker.render({
    elem: '#ID-colorpicker-demo-size-xs',
    size: 'xs' // mini 下拉框

<div class="demo-class-colorpicker" lay-options="{color: '#0000FF'}"></div>

<!-- import layui --> 
<script>
layui.use(function(){
  var colorpicker = layui.colorpicker;

  // 渲染
  colorpicker.render({
    elem: '.demo-class-colorpicker',
    done: function(color){
      console.log(this.elem, color);
    }
  });
