ColorWheel

ColorWheels allow users to adjust the hue of an HSL or HSB color value on a circular track.

installyarn add @react-spectrum/color
version3.0.0-rc.1
usageimport {ColorWheel} from '@react-spectrum/color'

Example#


<ColorWheel defaultValue="hsl(30, 100%, 50%)" />
<ColorWheel defaultValue="hsl(30, 100%, 50%)" />
<ColorWheel defaultValue="hsl(30, 100%, 50%)" />

Value#


A ColorWheel's value specifies the position of the ColorWheel's thumb on the track, and accepts a string or Color object. It is initialized as hsl(0, 100%, 50%) by default, but an alternative initial uncontrolled value can be provided using the defaultValue prop. Alternatively, a controlled value can be provided using the value prop. Note that only HSB(A) values are supported as valid values.

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.

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

function Example() {
  let [value, setValue] = React.useState(parseColor('hsl(30, 100%, 50%)'));
  return (
    <Flex gap="size-300" wrap>
      <Flex direction="column" alignItems="center">
        <label id="label-1">Hue (uncontrolled)</label>
        <ColorWheel
          defaultValue="hsl(30, 100%, 50%)"
          aria-labelledby="label-1" />
      </Flex>
      <Flex direction="column" alignItems="center">
        <label id="label-2">Hue (controlled)</label>
        <ColorWheel
          value={value}
          onChange={setValue}
          aria-labelledby="label-1" />
      </Flex>
    </Flex>
  );
}
import {parseColor} from '@react-stately/color';

function Example() {
  let [value, setValue] = React.useState(
    parseColor('hsl(30, 100%, 50%)')
  );
  return (
    <Flex gap="size-300" wrap>
      <Flex direction="column" alignItems="center">
        <label id="label-1">Hue (uncontrolled)</label>
        <ColorWheel
          defaultValue="hsl(30, 100%, 50%)"
          aria-labelledby="label-1"
        />
      </Flex>
      <Flex direction="column" alignItems="center">
        <label id="label-2">Hue (controlled)</label>
        <ColorWheel
          value={value}
          onChange={setValue}
          aria-labelledby="label-1"
        />
      </Flex>
    </Flex>
  );
}
import {parseColor} from '@react-stately/color';

function Example() {
  let [value, setValue] =
    React.useState(
      parseColor(
        'hsl(30, 100%, 50%)'
      )
    );
  return (
    <Flex
      gap="size-300"
      wrap
    >
      <Flex
        direction="column"
        alignItems="center"
      >
        <label id="label-1">
          Hue
          (uncontrolled)
        </label>
        <ColorWheel
          defaultValue="hsl(30, 100%, 50%)"
          aria-labelledby="label-1"
        />
      </Flex>
      <Flex
        direction="column"
        alignItems="center"
      >
        <label id="label-2">
          Hue
          (controlled)
        </label>
        <ColorWheel
          value={value}
          onChange={setValue}
          aria-labelledby="label-1"
        />
      </Flex>
    </Flex>
  );
}

HTML forms#

ColorWheel supports the name prop for integration with HTML forms. The value will be submitted as a number between 0 and 360 degrees.

<ColorWheel name="hue" />
<ColorWheel name="hue" />
<ColorWheel name="hue" />

Labeling#


By default, a localized string for the "hue" channel name is used as the aria-label for the ColorWheel. When a custom aria-label or aria-labelledby is provided, it should be localized accordingly.

Events#


ColorWheel supports two events: onChange and onChangeEnd. onChange is triggered whenever the ColorWheel'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 ColorWheel's value.

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

  return (
    <div>
      <ColorWheel
        value={currentValue}
        onChange={setCurrentValue}
        onChangeEnd={setFinalValue}
      />
      <pre>Current value: {currentValue.toString('hsl')}</pre>
      <pre>Final value: {finalValue.toString('hsl')}</pre>
    </div>
  );
}
function Example() {
  let [currentValue, setCurrentValue] = React.useState(
    parseColor('hsl(50, 100%, 50%)')
  );
  let [finalValue, setFinalValue] = React.useState(
    parseColor('hsl(50, 100%, 50%)')
  );

  return (
    <div>
      <ColorWheel
        value={currentValue}
        onChange={setCurrentValue}
        onChangeEnd={setFinalValue}
      />
      <pre>Current value: {currentValue.toString('hsl')}</pre>
      <pre>Final value: {finalValue.toString('hsl')}</pre>
    </div>
  );
}
function Example() {
  let [
    currentValue,
    setCurrentValue
  ] = React.useState(
    parseColor(
      'hsl(50, 100%, 50%)'
    )
  );
  let [
    finalValue,
    setFinalValue
  ] = React.useState(
    parseColor(
      'hsl(50, 100%, 50%)'
    )
  );

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

Testing#


The ColorWheel features a draggable handle that the user can interact with to change its color value. Please see the following section in the testing docs for more information on how to simulate this action in your test suite.

Please also refer to React Spectrum's test suite if you find that the above isn't sufficient when resolving issues in your own test cases.
