Elegant Mobile-compatible Color Picker Component – pickr

Description:

The pickr JavaScript library helps you create an elegant, customizable, touch-enabled color picker for your app.

Supports HEX, RGB, HSL, HSV, CMYK color formats and alpha channel.

Also provides a function that converts the default color values (HSVa) to HSLa, RGBa, HEX and CMYK values.

Supports both browser and node.js.

How to use it:

Install the pickr.

# NPM
$ npm install pickr-widget --save

Add the pickr’s JavaScript to the page.

<script src="dist/pickr.min.js"></script>

Add a theme CSS to the page.

<link href="themes/classic.min.css" rel="stylesheet">
<link href="themes/monolith.min.css" rel="stylesheet">
<link href="themes/nano.min.css" rel="stylesheet">

Create a container element to place the color picker.

<div class="example"></div>

Initialize the pickr to generate a default color picker.

const pickr = new Pickr({
      el: '.example',
      default: '#42445A' // default color
});

Customize the position of the color picker when triggered.

const pickr = new Pickr({
      el: '.example',
      default: '#42445A',
      position: 'middle', // or 'top', 'left'
});

Customize the color picker component.

const myPickr = new Pickr({

      el: '.example',
      components: {

        // color preview
        preview: true,

        // enables opacity slider
        opacity: true,

        // enables HUE slider
        hue: true,     // Hue slider

        // shows/hides controls
        output: {
          hex: true,
          rgba: true,
          hsla: true,
          hsva: true,
          cmyk: true, 
          input: true
        }
      }

});

Available color converters.

hsva.toHSVA()
hsva.toHSLA()
hsva.toRGBA()
hsva.toHEX() 
hsva.toCMYK()
hsva.clone()

Available options to customize the color picker.

const pickr = new Pickr({

  // custom classes
  appClass: null,

  // 'classic', 'monolith' or 'nano'
  theme: 'classic',

  // Selector or element which will be replaced with the actual color-picker.
  // Can be a HTMLElement.

      },
  },

  // Button strings, brings the possibility to use a language other than English.
