Usage

import { useState } from 'react';
import { DuotonePicker, DuotoneSwatch } from '@wordpress/components';

const DUOTONE_PALETTE = [
    { colors: [ '#8c00b7', '#fcff41' ], name: 'Purple and yellow', slug: 'purple-yellow' },
    { colors: [ '#000097', '#ff4747' ], name: 'Blue and red', slug: 'blue-red' },
];

const COLOR_PALETTE = [
    { color: '#ff4747', name: 'Red', slug: 'red' },
    { color: '#fcff41', name: 'Yellow', slug: 'yellow' },
    { color: '#000097', name: 'Blue', slug: 'blue' },
    { color: '#8c00b7', name: 'Purple', slug: 'purple' },
];

const Example = () => {
    const [ duotone, setDuotone ] = useState( [ '#000000', '#ffffff' ] );
    return (
        <>
            <DuotonePicker
                duotonePalette={ DUOTONE_PALETTE }
                colorPalette={ COLOR_PALETTE }
                value={ duotone }
                onChange={ setDuotone }
            />
            <DuotoneSwatch values={ duotone } />
        </>
    );
};

DuotonePicker Props

colorPalette

• Type: Object[]
• Required: Yes

Array of color presets of the form { color: '#000000', name: 'Black', slug: 'black' }.

duotonePalette

• Type: Object[]
• Required: Yes

Array of duotone presets of the form { colors: [ '#000000', '#ffffff' ], name: 'Grayscale', slug: 'grayscale' }.

value

• Type: string[]
• Required: Yes

An array of colors for the duotone effect.

selectedSlug

• Type: string
• Required: No

The slug of the selected duotone preset. When a non-empty selectedSlug is given, selection is decided strictly by slug, which keeps two presets holding the same pair of colors apart. Presets whose slug does not match will not appear selected in this mode, even if their colors match value.

An empty string is treated the same as undefined: selection falls back to matching by color value.

onChange

• Type: (value: string[] | 'unset' | undefined, index?: number | undefined, slug?: string | undefined) => void
• Required: Yes

The function called when the duotone colors change. It is passed the new value as an argument. When a preset from duotonePalette is picked, the second argument is its index and the third is its slug.

Both are omitted whenever no preset is being picked: the custom, unset and clear controls, and deselecting the currently selected preset, which reports undefined alone.

presentation: 'listbox' | 'toggle-buttons' | 'command-buttons'

Controls the predefined swatches’ interaction and accessibility semantics.

• listbox uses one tab stop for the picker. Arrow keys move between options. Options expose selection with aria-selected.

• toggle-buttons uses a tab stop for each swatch. Swatches expose selection with aria-pressed.

• command-buttons uses a tab stop for each swatch. Swatches do not expose selection. The value and selectedSlug props do not mark predefined swatches as selected, and activating a swatch always calls onChange with that swatch.

• Required: No

• Default: listbox

loop: boolean

Prevents arrow-key navigation from wrapping around. Only used with the listbox presentation.

• Required: No
• Default: true

DuotoneSwatch Props

values

• Type: string[] | null
• Required: No

An array of colors to show or null to show the placeholder swatch icon.
