Package Exports

toolcool-color-picker
toolcool-color-picker/dist/toolcool-color-picker.min.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (toolcool-color-picker) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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>

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);

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;
