Usage

ColorInput component supports Input and Input.Wrapper components features and all input element props. ColorInput documentation does not include all features supported by the component – see Input documentation to learn about all available features.

Input description

Variant
Size
Radius
import { ColorInput } from '@mantine/core';

function Demo() {
  return (
    <ColorInput
      label="Input label"
      description="Input description"
      placeholder="Input placeholder"
    />
  );
}

Controlled

import { useState } from 'react';
import { ColorInput } from '@mantine/core';

function Demo() {
  const [value, setValue] = useState('');
  return <ColorInput value={value} onChange={setValue} />;
}

Formats

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

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

function Demo() {
  return <ColorInput defaultValue="#C5D899" />;
}

Preserve invalid input

By default, ColorInput will revert the value on blur to the last known valid value. To change this behavior and keep invalid value, set fixOnBlur={false}:

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

function Demo() {
  return <ColorInput fixOnBlur={false} label="Value is not fixed on blur" placeholder="May contain invalid value" />;
}

onChangeEnd

onChangeEnd is called when user stops dragging slider or changes input value. It is useful when you need to update color only when user finished interaction with the component:

Change end value: #FFFFFF

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

function Demo() {
  const [changeEndValue, setChangeEndValue] = useState('#FFFFFF');

  return (
    <>
      <Text mb="md">
        Change end value: <b>{changeEndValue}</b>
      </Text>

      <ColorInput
        label="Pick color"
        placeholder="Pick color"
        defaultValue="#FFFFFF"
        onChangeEnd={setChangeEndValue}
      />
    </>
  );
}

Disable free input

To disable free input set disallowInput prop:

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

function Demo() {
  return <ColorInput disallowInput />;
}

With swatches

You can add any amount of predefined color swatches:

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

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

By default, there will be 7 swatches per row, you can change this with swatchesPerRow prop, like in ColorPicker component:

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']} />
  );
}

If you need to restrict color picking to certain colors – disable color picker and disallow free input:

import { ColorInput, DEFAULT_THEME } from '@mantine/core';

function Demo() {
  return (
    <ColorInput
      placeholder="Pick color"
      label="Your favorite color"
      disallowInput
      withPicker={false}
      swatches={[
        ...DEFAULT_THEME.colors.red,
        ...DEFAULT_THEME.colors.green,
        ...DEFAULT_THEME.colors.blue,
      ]}
    />
  );
}

Close dropdown on color swatch click

To close the dropdown when one of the color swatches is clicked, set closeOnColorSwatchClick prop:

import { ColorInput, DEFAULT_THEME } from '@mantine/core';

function Demo() {
  return (
    <ColorInput
      closeOnColorSwatchClick
      label="Dropdown is closed when color swatch is clicked"
      placeholder="Click color swatch"
      swatches={[
        ...DEFAULT_THEME.colors.red,
        ...DEFAULT_THEME.colors.green,
        ...DEFAULT_THEME.colors.blue,
      ]}
    />
  );
}

Hide dropdown

To hide dropdown, set withPicker={false}:

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

function Demo() {
  return (
    <ColorInput withPicker={false} pointer label="Without dropdown" placeholder="Enter value" />
  );
}

Eye dropper

By default, if EyeDropper API is available, eye dropper icon will be displayed at the right section of the input. To disable it, set withEyeDropper={false}:

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

function Demo() {
  return <ColorInput withEyeDropper={false} label="Without eye dropper" placeholder="Not fun" />;
}

Change eye dropper icon

You can replace eye dropper icon with any React node using eyeDropperIcon prop:

import { ColorInput, rem } from '@mantine/core';
import { IconFocus2 } from '@tabler/icons-react';

function Demo() {
  return (
    <ColorInput
      eyeDropperIcon={<IconFocus2 style={{ width: rem(18), height: rem(18) }} stroke={1.5} />}
      label="With custom eye dropper icon"
      placeholder="Pick color"
    />
  );
}

Left and right sections

ColorInput supports leftSection and rightSection props. These sections are rendered with absolute position inside the input wrapper. You can use them to display icons, input controls or any other elements.

You can use the following props to control sections styles and content:

  • rightSection/leftSection – React node to render on the corresponding side of input
  • rightSectionWidth/leftSectionWidth – controls width of the right section and padding on the corresponding side of the input. By default, it is controlled by component size prop.
  • rightSectionPointerEvents/leftSectionPointerEvents – controls pointer-events property of the section. If you want to render a non-interactive element, set it to none to pass clicks through to the input.

Note that by default, ColorPicker has color preview in the left section and eye dropper button in the right section. You can replace these elements with any React node using leftSection and rightSection props:

import { ColorInput, rem } from '@mantine/core';
import { IconColorPicker } from '@tabler/icons-react';

function Demo() {
  const icon = <IconColorPicker style={{ width: rem(18), height: rem(18) }} stroke={1.5} />;

  return (
    <>
      <ColorInput
        label="With custom left section"
        placeholder="Replaces color swatch"
        leftSection={icon}
        withEyeDropper={false}
      />
      <ColorInput
        label="With custom right section"
        placeholder="Replaces eye dropper"
        rightSection={icon}
        mt="md"
      />
    </>
  );
}

Error state

Invalid name

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

function Demo() {
  return (
    <>
      <ColorInput label="Boolean error" placeholder="Boolean error" error />
      <ColorInput
        mt="md"
        label="With error message"
        placeholder="With error message"
        error="Invalid name"
      />
    </>
  );
}

Disabled state

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

function Demo() {
  return <ColorInput disabled label="Disabled input" placeholder="Disabled input" />;
}

Read only

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

function Demo() {
  return <ColorInput readOnly label="Cannot modify value" defaultValue="#F0FCFE" />;
}

Styles API

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

Description

Error

Component Styles API

Hover over selectors to highlight corresponding elements

/*
 * Hover over selectors to apply outline styles
 *
 */

Get element ref

import { useRef } from 'react';
import { ColorInput } from '@mantine/core';

function Demo() {
  const ref = useRef<HTMLInputElement>(null);
  return <ColorInput ref={ref} />;
}

Accessibility

If ColorInput is used without label prop, it will not be announced properly by screen reader:

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

// Inaccessible input – screen reader will not announce it properly
function Demo() {
  return <ColorInput />;
}

Set aria-label to make the input accessible. In this case label will not be visible, but screen reader will announce it:

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

// Accessible input – it has aria-label
function Demo() {
  return <ColorInput aria-label="My input" />;
}

If label prop is set, input will be accessible it is not required to set aria-label:

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

// Accessible input – it has associated label element
function Demo() {
  return <ColorInput label="My input" />;
}
