Quickstart

var ColorPicker = require('simple-color-picker-jq');

var colorPicker = new ColorPicker();

And include simple-color-picker.css in your html or import it in your css.

You can retrieve the current color in different formats by using these convenient methods:

• colorPicker.getColor(); // output depends on previously inputed color format
• colorPicker.getHexString(); // #FFFFFF
• colorPicker.getHexNumber(); // 0xFFFFFF
• colorPicker.getRGB(); // {r: 255, g: 255, b: 255}
• colorPicker.getHSV(); // {h: 0, s: 0, v: 1}

Options

Options you can pass to constructor in an object like so :

var colorPicker = new ColorPicker({
  color: '#FF0000',
  background: '#454545',
  el: $('body'),
  width: 200,
  height: 200
});

None of these options are mendatory.

color

The default color that the colorpicker will display. Default is #FFFFFF. It can be a hexadecimal number or an hex String.
