Basic Usage

Download the latest toolcool-color-picker.min.js script:

Add the following html to the page:

<toolcool-color-picker color="#e76ff1"></toolcool-color-picker>

<script type="text/javascript" src="toolcool-color-picker.min.js"></script>

Or with other color formats:

<toolcool-color-picker color="rgb(96, 245, 66)"></toolcool-color-picker>
<toolcool-color-picker color="rgba(96, 245, 66, 1)"></toolcool-color-picker>
<toolcool-color-picker color="hsv(110, 73%, 96%)"></toolcool-color-picker>
<toolcool-color-picker color="hsva(110, 73%, 96%, 1)"></toolcool-color-picker>
<toolcool-color-picker color="hsl(110, 90%, 61%)"></toolcool-color-picker>
<toolcool-color-picker color="hsla(110, 90%, 61%, 1)"></toolcool-color-picker>

<script type="text/javascript" src="toolcool-color-picker.min.js"></script>

Color picker popup can be aligned to the right:

<toolcool-color-picker color="rgb(255, 200, 10)" popup-position="right"></toolcool-color-picker>

CDN

The ToolCool Color Picker is also available in the jsDelivr CND:

<toolcool-color-picker color="#e76ff1"></toolcool-color-picker>

<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/toolcool-color-picker/dist/toolcool-color-picker.min.js"></script>

Node.js usage

Color picker may also be included as a node module using npm:

npm i toolcool-color-picker

or with Yarn:

yarn add toolcool-color-picker

And then you can include it in your application like this:

import 'toolcool-color-picker';

NPM package can fe found here.

APIs

You can control the color picker by referencing the toolcool-color-picker HTML tag.

<toolcool-color-picker color="#e76ff1" id="color-picker-1"></toolcool-color-picker>

<script type="text/javascript" src="toolcool-color-picker.min.js"></script>
<script>
    // get the reference
    const $colorPicker = document.getElementById('color-picker-1');
    
    // change color
    $colorPicker.color = '#60f542';
    
    // get color
    console.log($colorPicker.rgba);
</script>

APIs: Listen to the change event

// listen to the color change event
const $colorPicker = document.getElementById('color-picker');

// @param {evt} CustomEvent
$colorPicker.addEventListener('change', (evt) => {
    
    console.log(evt.detail.hex);
    console.log(evt.detail.hex8);
    console.log(evt.detail.rgb);
    console.log(evt.detail.rgba);
    console.log(evt.detail.hsl);
    console.log(evt.detail.hsla);
    console.log(evt.detail.hsv);
    console.log(evt.detail.hsva);
    console.log(evt.detail.color);
});

APIs: Change Color

The color picker uses the awesome TinyColor library for color manipulation. Each color format supported by the TinyColor library can be passed in a color property:

const $colorPicker = document.getElementById('color-picker');

// HEX format
$colorPicker.color = '#60f542';

// OR HEX with opacity
$colorPicker.color = '#60f542ff';

// OR rgb
$colorPicker.color = 'rgb(96, 245, 66)';

// OR rgb with opacity
$colorPicker.color = 'rgba(96, 245, 66, 1)';

// OR hsv
$colorPicker.color = 'hsv(110, 73%, 96%)';

// OR hsv with opacity
$colorPicker.color = 'hsva(110, 73%, 96%, 1)';

// OR hsl
$colorPicker.color = 'hsl(110, 90%, 61%)';

// OR hsl with opacity
$colorPicker.color = 'hsla(110, 90%, 61%, 1)';

APIs: Get current color in different formats

const $colorPicker = document.getElementById('color-picker');
$colorPicker.color = '#367E95';

console.log($colorPicker.hex); // #367E95

console.log($colorPicker.hex8); // #367E95FF

console.log($colorPicker.rgb); // rgb(54, 126, 149)

console.log($colorPicker.rgba); // rgba(54, 126, 149, 1)

console.log($colorPicker.hsl); // hsl(195, 47%, 40%)

console.log($colorPicker.hsla); // hsla(195, 47%, 40%, 1)

console.log($colorPicker.hsv); // hsv(195, 64%, 58%)

console.log($colorPicker.hsva); // hsva(195, 64%, 58%, 1)

You can also access the color object of the TinyColor library. It should only be used to get color values and should not be modified directly.

console.log($colorPicker.color); 

APIs: Popup

Open or close color picker popup with the following API:

<toolcool-color-picker color="#e76ff1" id="color-picker"></toolcool-color-picker>
<script src="js/toolcool-color-picker.min.js"></script>

<script>
    const $colorPicker = document.getElementById('color-picker');

    // open color picker popup
    $colorPicker.opened = true;

    // close color picker popup
    $colorPicker.opened = false;
</script>

Styles

It's possible to control color picker styles through CSS variables:

:root{
    /* button */
    --tool-cool-color-picker-btn-bg: #b9b9b9;
    --tool-cool-color-picker-btn-border-color: #000;
    --tool-cool-color-picker-btn-border-color-inner: #363636;
    --tool-cool-color-picker-btn-border-radius: 1rem;
    --tool-cool-color-picker-btn-border-radius-inner: 1rem;

    /* popup */
    --tool-cool-color-picker-popup-bg: #b9b9b9;
    --tool-cool-color-picker-popup-border-color: #000;

    /* fields */
    --tool-cool-color-picker-field-border-color: #363636;
    --tool-cool-color-picker-field-label-color: #1a3c6e;
}

It's also possible to use CSS variables as inline styles in the following way:

<toolcool-color-picker 
        color="rgb(255, 200, 10)" 
        style="--tool-cool-color-picker-btn-bg: #fff"></toolcool-color-picker>

Button width, height, and padding

Thanks to MGarcia93 for contributing to this section.

Button size can be changed using button-width, button-height, and button-padding attributes.

<toolcool-color-picker
        color="#B48CF4"
        button-width="2rem"
        button-height="1rem"
        button-padding="2px"></toolcool-color-picker>

It's also possible to use the following predefined values:

Attribute Value	The result size
sm	0.875rem
md	1.2rem
lg	1.5rem
xl	2.25rem
2xl	3rem
3xl	3.75rem
4xl	4.5rem

For example:

<toolcool-color-picker
        color="#C0F16F"
        button-width="xl"
        button-height="lg"
        button-padding="3px"></toolcool-color-picker>

TypeScript Usage

import 'toolcool-color-picker';
import ColorPicker from 'toolcool-color-picker';

// ...

const $colorPicker = document.getElementById('color-picker-1') as ColorPicker;

$colorPicker.addEventListener('change', (evt: Event) => {
    const customEvent = evt as CustomEvent;
    console.log(customEvent.detail.rgba);
});

$colorPicker.hex = '#fefefe';

Usage with React and TypeScript

import 'toolcool-color-picker';

declare global {
    namespace JSX {
        interface IntrinsicElements {
            'toolcool-color-picker': any;
        }
    }
}

const ColorPickerExample = () => {

    const colorPickerRef = useRef<HTMLElement>();

    useEffect(() => {

        const colorPicker = colorPickerRef.current;

        const onColorChange = (evt: Event) => {
            const customEvent = evt as CustomEvent;
            console.log(customEvent.detail.rgba);
        };

        colorPicker?.addEventListener('change', onColorChange);

        return () => {
            colorPicker?.removeEventListener('change', onColorChange);
        };
    }, []);

    return (
        <toolcool-color-picker ref={ colorPickerRef }  color="#efefef" />;
    )
};

export default ColorPickerExample;
