Usage

1<hex-color-picker color="#1e88e5"></hex-color-picker>
2<script type="module">
3  import 'vanilla-colorful';
4
5  const picker = document.querySelector('hex-color-picker');
6  picker.addEventListener('color-changed', (event) => {
7    // get updated color value
8    const newColor = event.detail.value;
9  });
10
11  // get current color value
12  console.log(picker.color);
13</script>

ES modules

vanilla-colorful is authored using ES modules which are natively supported by modern browsers. However, all the code examples listed here use so-called "bare module specifiers": import 'vanilla-colorful'.

There is now a feature in the HTML Standard called import maps that enables resolving bare module specifiers without requiring any tools. As of October 2022, import maps are not yet shipped in all browsers.

In the meantime, we recommend using one of the tools that leverage ES modules based development, such as vite, @web/dev-server, or wmr. None of these tools are needed when importing from CDN.

Supported color models

The default vanilla-colorful's input/output format is a HEX string (like #ffffff). In case if you need another color model, we provide 12 additional color picker bundles.

1<rgba-color-picker></rgba-color-picker>
2<script type="module">
3  import 'vanilla-colorful/rgba-color-picker.js';
4
5  const picker = document.querySelector('rgba-color-picker');
6  picker.color = { r: 50, g: 100, b: 150, a: 1 };
7</script>

Overriding styles

vanilla-colorful exposes CSS Shadow Parts allowing to override the default styles:

1hex-color-picker {
2  height: 250px;
3}
4
5hex-color-picker::part(saturation) {
6  bottom: 30px;
7  border-radius: 3px 3px 0 0;
8}
9
10hex-color-picker::part(hue) {
11  height: 30px;
12  border-radius: 0 0 3px 3px;
13}
14
15hex-color-picker::part(saturation-pointer) {
16  border-radius: 5px;
17}
18
19hex-color-picker::part(hue-pointer) {
20  border-radius: 2px;
21  width: 15px;
22  height: inherit;
23}

HEX input

vanilla-colorful provides an additional <hex-input> element that can be used to type a color:

1<hex-input color="#1e88e5"></hex-input>
2<script type="module">
3  import 'vanilla-colorful/hex-input.js';
4
5  const input = document.querySelector('hex-input');
6  input.addEventListener('color-changed', (event) => {
7    const newColor = event.detail.value;
8  });
9</script>

<hex-input> renders an unstyled <input> element inside a slot and exposes it for styling using part. You can also pass your own <input> element as a child if you want to fully configure it.

In addition to color property, <hex-input> supports the following boolean properties:

Base classes

vanilla-colorful provides a set of base classes that can be imported without registering custom elements. This is useful if you want to create your own color picker with a different tag name.

1import { RgbBase } from 'vanilla-colorful/lib/entrypoints/rgb.js';
2
3customElements.define('custom-color-picker', class extends RgbBase {});

Code Recipes

• Custom styles and layout
• Prevent flash of unstyled content
• Prevent flash of unstyled content (picker with alpha)
• Text field to be able to type/copy/paste a color

TypeScript support

vanilla-colorful supports TypeScript and ships with types in the library itself; no need for any other install.

1import type { HslColor } from 'vanilla-colorful/hsl-color-picker';
2
3const myHslValue: HslColor = { h: 0, s: 0, l: 0 };

1const picker = document.querySelector('rgba-color-picker');
2
3picker.addEventListener('color-changed', (event) => {
4  console.log(event.detail.value.a); // (property) RgbaColor.a: number
5});

Browser support

vanilla-colorful uses Custom Elements and Shadow DOM, and does not support IE11 or legacy Edge.

Why vanilla-colorful?

vanilla-colorful has all the benefits of react-colorful with one important difference.

While react-colorful claims to have zero dependencies, it still expects you to use React or Preact. This means that Angular, Vue, Svelte or vanilla JS users would have an extra dependency in their apps.

Now when all the evergreen browsers support standards based Custom Elements, it's perfect time to build such tiny and lightweight UI controls as web components rather than framework components.
