Usage

rgba(47, 119, 150, 0.7)

import { useState } from 'react';
import { ColorPicker, Text } from '@mantine/core';

function Demo() {
  const [value, onChange] = useState('rgba(47, 119, 150, 0.7)');

  return (
    <>
      <ColorPicker format="rgba" value={value} onChange={onChange} />
      <Text>{value}</Text>
    </>
  );
}

Color format

ColorPicker supports hex, hexa, rgb, rgba, hsl and hsla color formats. Slider to change opacity and color preview are displayed only for hexa, rgba and hsla formats:

#C5D899

import { ColorPicker } from '@mantine/core';

function Demo() {
  return <ColorPicker />;
}

With swatches

You can add predefined color swatches with swatches prop:

import { ColorPicker } from '@mantine/core';

function Demo() {
  return (
    <ColorPicker
      format="hex"
      swatches={['#2e2e2e', '#868e96', '#fa5252', '#e64980', '#be4bdb', '#7950f2', '#4c6ef5', '#228be6', '#15aabf', '#12b886', '#40c057', '#82c91e', '#fab005', '#fd7e14']}
    />
  );
}

By default, ColorPicker will display 7 swatches per row, you can configure it with swatchesPerRow prop:

Swatches per row
import { ColorPicker } from '@mantine/core';

function Demo() {
  return (
    <ColorPicker format="hex" swatches={['#2e2e2e', '#868e96', '#fa5252', '#e64980', '#be4bdb', '#7950f2', '#4c6ef5', '#228be6', '#15aabf', '#12b886', '#40c057', '#82c91e', '#fab005', '#fd7e14']} />
  );
}

To display swatches without picker set withPicker={false} and fullWidth props:

#fff

import { useState } from 'react';
import { DEFAULT_THEME, ColorPicker, Text } from '@mantine/core';

function Demo() {
  const [value, onChange] = useState('#fff');

  return (
    <>
      <ColorPicker
        format="hex"
        value={value}
        onChange={onChange}
        withPicker={false}
        fullWidth
        swatches={[
          ...DEFAULT_THEME.colors.red.slice(0, 7),
          ...DEFAULT_THEME.colors.green.slice(0, 7),
          ...DEFAULT_THEME.colors.blue.slice(0, 7),
        ]}
      />

      <Text>{value}</Text>
    </>
  );
}

Size

ColorPicker has 5 predefined sizes: xs, sm, md, lg and xl:

Size
import { ColorPicker } from '@mantine/core';

function Demo() {
  return <ColorPicker />;
}

fullWidth

Set fullWidth prop to stretch component to 100% of parent width. In this case the picker will not have fixed width, but you can still use size prop to control sizes of sliders.

import { ColorPicker } from '@mantine/core';

function Demo() {
  return <ColorPicker fullWidth size="lg" format="rgba" />;
}

Styles API

ColorPicker supports Styles API, you can add styles to any inner element of the component withclassNames prop. Follow Styles API documentation to learn more.
