   var pluginName = new ewColorPicker(option);//option is the configuration object, see above for details

tips: It should be noted that starting from version 1.6.4, if there are multiple dom elements passed in, only the first dom element will be rendered as a colorPicker. If multiple colorPickers need to be rendered, an array can be used for instance. E.g:

   let els = document.querySelectorAll('.demo');
   els.forEach(item => {
     new ewColorPicker(item);
     //or new ewColorPicker({
    //  el:item,
    //  }) //and the configuration
   })
