Example#

<ColorArea defaultValue="#7f0000" />

<ColorArea defaultValue="#7f0000" />

<ColorArea defaultValue="#7f0000" />

Value#

A ColorArea requires either an uncontrolled default value or a controlled value, provided using the defaultValue or value props respectively. The value provided to either of these props should be a color string or Color object. xChannel and yChannel props may also be provided to specify which color channels the color area should display, and the direction of each channel in the color gradient. This must be one of the channels included in the color value, for example, for RGB colors, the "red", "green", and "blue" channels are available. For a full list of supported channels, see the Props table below.

In the example below, the parseColor function is used to parse the initial color from a HSL string so that value's type remains consistent.

Labeling#

By default, ColorArea uses an aria-label for the localized string "Color Picker", which labels the visually hidden <input> elements for the two color channels, or on mobile devices, the group containing them. If you wish to override this with a more specific label, an aria-label or aria-labelledby prop may be passed to further identify the element to assistive technologies. For example, for a ColorArea that adjusts a background color you might pass the aria-label prop, "Background color", which ColorArea will return as the aria-label prop "Background color, Color picker". If you provide your own aria-label or aria-labelledby, be sure to localize the string or labeling element appropriately.

Note that like ColorWheel, ColorArea does not include an integrated visible label or a label prop. Use aria-labelledby to label the ColorArea using the IDREF assigned to a visible label.

import {ColorArea} from '@react-spectrum/color';
import {Flex} from '@react-spectrum/layout';
import {Label} from '@react-spectrum/label';

<Flex gap="size-300" wrap alignItems="end">
  <ColorArea
    aria-label="Background color"
    defaultValue="hsl(0, 100%, 50%)"
    xChannel="saturation"
    yChannel="lightness" />
  <div>
    <Label
      id="hsl-aria-labelledby-id">Background color</Label>
    <ColorArea
      aria-labelledby="hsl-aria-labelledby-id"
      defaultValue="hsl(0, 100%, 50%)"
      xChannel="saturation"
      yChannel="lightness" />
  </div>
</Flex>

import {ColorArea} from '@react-spectrum/color';
import {Flex} from '@react-spectrum/layout';

Accessibility#

Role description#

In order to communicate to a screen reader user that the ColorArea adjusts in two dimensions, ColorArea provides an aria-roledescription, using the localized string "2D Slider", on each of the visually hidden <input> elements.

Value formatting#

The aria-valuetext of each <input> element within the ColorArea is formatted according to the user's locale automatically. It will include the localized color channel name and current value for each channel, with the channel name and value that the <input> element controls coming before the channel name and value for the adjacent <input> element. For example, for an RGB ColorArea where the xChannel is "blue", the yChannel is "green", when the current selected color is yellow (rgb(255, 255, 0)), the <input> representing the blue channel will have aria-valuetext to announce as "Blue: 0, Green: 255", and the <input> representing the green channel will have aria-valuetext to announce as "Green: 255, Blue: 0".

Internationalization#

For languages that are read right-to-left (e.g. Hebrew and Arabic), the layout of the ColorArea is automatically flipped. As mentioned previously, ColorArea automatically uses the current locale to format the aria-valuetext for each of the <input> element with the channel name and current value.

Events#

ColorArea supports two events: onChange and onChangeEnd. onChange is triggered whenever the ColorArea's handle is dragged, and onChangeEnd is triggered when the user stops dragging the handle. Both events receive a Color object as a parameter.

The example below uses onChange and onChangeEnd to update two separate elements with the ColorArea's value.

import {ColorArea} from '@react-spectrum/color';
import {parseColor} from '@react-stately/color';

function Example() {
  let [currentValue, setCurrentValue] = React.useState(
    parseColor('hsl(50, 100%, 50%)')
  );
  let [finalValue, setFinalValue] = React.useState(
    parseColor('hsl(50, 100%, 50%)')
  );

  return (
    <div>
      <ColorArea
        value={currentValue}
        onChange={setCurrentValue}
        onChangeEnd={setFinalValue}
      />
      <pre>Current value: {currentValue.toString('hsl')}</pre>
      <pre>Final value: {finalValue.toString('hsl')}</pre>
    </div>
  );
}

import {ColorArea} from '@react-spectrum/color';
import {parseColor} from '@react-stately/color';

function Example() {
  let [currentValue, setCurrentValue] = React.useState(
    parseColor('hsl(50, 100%, 50%)')
  );
  let [finalValue, setFinalValue] = React.useState(
    parseColor('hsl(50, 100%, 50%)')
  );

  return (
    <div>
      <ColorArea
        value={currentValue}
        onChange={setCurrentValue}
        onChangeEnd={setFinalValue}
      />
      <pre>Current value: {currentValue.toString('hsl')}</pre>
      <pre>Final value: {finalValue.toString('hsl')}</pre>
    </div>
  );
}

import {ColorArea} from '@react-spectrum/color';
import {parseColor} from '@react-stately/color';

function Example() {
  let [
    currentValue,
    setCurrentValue
  ] = React.useState(
    parseColor(
      'hsl(50, 100%, 50%)'
    )
  );
  let [
    finalValue,
    setFinalValue
  ] = React.useState(
    parseColor(
      'hsl(50, 100%, 50%)'
    )
  );

  return (
    <div>
      <ColorArea
        value={currentValue}
        onChange={setCurrentValue}
        onChangeEnd={setFinalValue}
      />
      <pre>Current value: {currentValue.toString('hsl')}</pre>
      <pre>Final value: {finalValue.toString('hsl')}</pre>
    </div>
  );
}

Creating a color picker#

To build a fully functional color picker, combine a ColorArea, which adjusts two channels of a color value stored in state, with a separate control, like a ColorSlider or ColorWheel, for adjusting the value of the third channel within the color space for the color value stored in state. The current color space for a color can be returned using the color.getColorSpace method. An array of channel names for a color can be returned using the color.getColorChannels method. To get a localized channel name to use as a label, you can use the color.getChannelName method.

RGBA#

This example shows how you could build an RGB color picker using a color area and color sliders bound to the same color value in state. The parseColor function is used to parse the initial color from a hex value, stored in state. The value and onChange props of both the ColorArea and ColorSlider are used to make the components controlled, so that they both update when the color is modified.

import {ColorArea, ColorSlider} from '@react-spectrum/color';
import {Flex} from '@react-spectrum/layout';
import {Label} from '@react-spectrum/label';
import {parseColor} from '@react-stately/color';

function Example() {

  let [redChannel, greenChannel, blueChannel] = color.getColorChannels();
  return (
    <fieldset style={{ border: 0 }}>
      <legend>{color.getColorSpace().toUpperCase()}A Example</legend>
      <Flex direction="column">
        <ColorArea

          yChannel={greenChannel}
          value={color}
          onChange={setColor}
        />
        <ColorSlider channel={blueChannel} value={color} onChange={setColor} />
        <ColorSlider channel="alpha" value={color} onChange={setColor} />
        <p>Current value: {color.toString('css')}</p>
