Angular Radial Color Picker

Introduction

Great UX starts with two basic principles - ease of use and simplicity. Selecting a color should be as easy as moving a slider, clicking a checkbox or pressing a key just like other basic form elements behave.

This is a flexible and elegant material design color picker. Developed with mobile devices and keyboard usage in mind. Key features:

Small size - 5.4 KB gzipped (JS and CSS combined)
Supports touch devices
Responsive size
Optimized animations
Supports CommonJS and ES Modules
Ease of use
- Double click anywhere to move the knob to a color
- Tab to focus the picker
- Up or Right arrow key to increase hue. Hold Ctrl to go quicker
- Bottom or Left arrow key decrease hue. Hold Ctrl to go quicker
- Enter to select a color and close the picker or to open it
- Mouse ScrollUp to increase and ScrollDown to decrease hue (Opt-in)

Usage

With Module Build System

Color Picker on npm

npm install -S angular-radial-color-picker

And in your app:

import angular from 'angular';
import colorPicker from 'angular-radial-color-picker';
import 'angular-radial-color-picker/dist/css/color-picker.scss';

angular.module('app', [colorPicker]);

Depending on your build tool of choice you have to setup the appropriate Webpack loaders or Rollup plugins. The color picker was tested with the latest versions of sass-loader and rollup-plugin-postcss.

UMD version

You can also use the minified sources directly:

<head>
    <link href="https://unpkg.com/angular-radial-color-picker@latest/dist/css/color-picker.min.css" rel="stylesheet">
</head>
<body ng-app="app">
    <color-picker></color-picker>

    <script src="https://unpkg.com/[email protected]/angular.min.js"></script>
    <script src="https://unpkg.com/angular-radial-color-picker@latest/dist/color-picker.umd.min.js"></script>
    <script>
        angular.module('app', ['color.picker.core']);
    </script>
</body>

Options

<color-picker> component has several attributes, all of which are optional. See the example which uses all options.

| Options | Type | Default/Description | |------------|--------|---------| | color | Object | Object for initializing/changing the color of the picker. Defaults to red: {hue: 0, saturation: 100, luminosity: 50, alpha: 1}. | | on-select | Function | Callback which is triggered when a color is selected. | | on-color-change | Function | A function to invoke when color is changed (i.e. on rotation). | | mouse-scroll | Boolean | Use wheel (scroll) event to rotate. Defaults to false. | | scroll-sensitivity | Number | Amount of degrees to rotate the picker with keyboard and/or wheel. Defaults to 2 degrees. |

Events

For maximum flexibility the component utilizes the pub/sub pattern. For easier communication a set of events are provided that can even programmatically open or close the picker without interacting with the UI. All events carry the current (selected) color in the event data payload.

| Name | Description | |------------|-------------| | color-picker.show | Fires when the color picker is about to show and before any animation is started. | | color-picker.shown | Fires when the color picker is shown and has finished animating. | | color-picker.selected | Fires when a color is selected via the middle selector. Event is fired right before hide. | | color-picker.hide | Fires when the color picker is about to hide and before any animation is started. | | color-picker.hidden | Fires when the color picker is hidden and has finished animating. | | color-picker.open | Programatically opens the color picker if it's not already opened. | | color-picker.close | Programatically closes the color picker if it's not already closed. |

Example:

// Assign the selected color to the ViewModel and log it to the console
$scope.$on('color-picker.selected', function(ev, color) {
    vm.selectedColor = 'hsla(' + color.hue + ', ' + color.saturation + '%, ' + color.luminosity + '%, ' + color.alpha + ')';
    console.log('Selected color:', color);
});

// The good'n'tested "poke-it-with-a-stick" method:
$scope.$emit('color-picker.open');

Styling/Sizing

The color picker has a default width/height of 280px, but can also be sized via CSS. For example:

color-picker {
    width: 350px;
    height: 350px;
}

If you want a percentage based size you can use this neat little trick with 1:1 aspect ratio box of 40% width of the parent element:

color-picker {
    height: 0;
    width: 40%;
    padding-bottom: 40%;
}
