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 = '#FBF330';

    // 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 API

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);
                    

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 Size

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

                            <toolcool-color-picker
    color="#B48CF4"
    button-width="5rem"
    button-height="3rem"
    button-padding="5px"></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('get-color-picker') as ColorPicker;

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

$colorPicker.hex = '#fefefe';
