API#

useColorSlider(
  (props: ColorSliderAriaOptions,
  , state: ColorSliderState
)): ColorSliderAria

Features#

The <input type="color"> HTML element can be used to build a color picker, however it is very inconsistent across browsers and operating systems and consists of a complete color picker rather than a single color channel slider. useColorSlider helps achieve accessible and touch-friendly color sliders that can be styled as needed.

Support for adjusting a single channel of RGBA, HSLA, and HSBA colors
Support for mouse, touch, and keyboard via the useMove hook
Multi-touch support for dragging multiple sliders at once
Pressing on the track moves the thumb to that position
Supports using the arrow keys, as well as page up/down, home, and end keys
Support for both horizontal and vertical orientations
Support for custom step values with handling for rounding errors
Support for disabling the color slider
Prevents text selection while dragging
Exposed to assistive technology as a slider element via ARIA
Uses a hidden native input element to support touch screen readers
Automatic ARIA labeling using localized channel names by default
Support for visually labeling the slider
Support for displaying the current value using an <output> element
Internationalized number formatting based on the color channel type
Support for mirroring in RTL locales

Anatomy#

A color slider consists of a track element and a thumb that the user can drag to change a single channel of a color value. It may also include optional label and <output> elements to display the color channel name and current numeric value, respectively. A visually hidden <input> element is used to represent the value to assistive technologies.

useColorSlider returns props that you should spread onto the appropriate elements:

Name	Type	Description
`labelProps`	`HTMLAttributes<HTMLElement>`	Props for the label element.
`trackProps`	`HTMLAttributes<HTMLElement>`	Props for the track element.
`thumbProps`	`HTMLAttributes<HTMLElement>`	Props for the thumb element.
`inputProps`	`HTMLAttributes<HTMLElement>`	Props for the visually hidden range input element.
`outputProps`	`HTMLAttributes<HTMLElement>`	Props for the output element, displaying the value of the color slider.

State is managed by the useColorSliderState hook from @react-stately/color. The state object should be passed as an option to useColorSlider

By default, useColorSlider provides an aria-label for the localized color channel name. If you wish to display a visual label, or override this with a more specific label, a label, aria-label or aria-labelledby prop may be passed instead.

Example#

This example shows how to build a horizontal color slider. It also includes a label which can be clicked to focus the thumb. Styling for the track background and positioning of the thumb are provided by useColorSlider in the returned style prop for each element.

If no label prop is given, it uses the Color object to get a localized string for the channel name using the getChannelName method. In addition, an <output> element is used to display the current channel value as text. This is formatted using the Color object's formatChannelValue method, which formats the value according to the channel type and locale settings.

The <input> element inside the thumb is used to represent the color slider to assistive technology, and is hidden from view using the VisuallyHidden component. The thumb also uses the useFocusRing hook to grow in size when it is keyboard focused (try tabbing to it).

Vertical#

This example shows how to build a vertical color slider. The main difference from horizontal color sliders is the addition of the orientation: 'vertical' option to useColorSlider. This automatically adjusts the internal positioning and dragging logic. Additionally, this example does not have a visible label or <output> element. This can be done by simply not using the returned labelProps and outputProps. The color slider will have a default aria-label using the localized channel name, which can be overridden by passing an aria-label prop to useColorSlider.

function ColorSlider(props) {
  let {locale} = useLocale();
  let state = useColorSliderState({...props, locale});
  let trackRef = React.useRef();
  let inputRef = React.useRef();
  let {groupProps, trackProps, thumbProps, inputProps} = useColorSlider(
    {
      ...props,
      orientation: 'vertical',
      trackRef,
      inputRef
    },
    state
  );

Usage#

The following examples show how to use the ColorSlider component created in the above example.

RGBA#

This example shows how you could build an RGBA color picker using four 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 ColorSlider are used to make the sliders controlled, so that they all update when the color is modified.

    )
  );
  return (
    <>
      <ColorSlider
        channel="hue"
        value={color}
        onChange={
          setColor
        }
      />
      <ColorSlider

      />
      <ColorSlider
        channel="alpha"
        value={color}
        onChange={
          setColor
        }
      />
    </>
  );
}

HSBA#

This example shows how to build an HSBA color picker.

function Example() {
  let [color, setColor] = React.useState(parseColor('hsb(0, 100%, 50%)'));
  return (
    <>
      <ColorSlider channel="hue" value={color} onChange={setColor} />
      <ColorSlider channel="saturation" value={color} onChange={setColor} />
      <ColorSlider channel="brightness" value={color} onChange={setColor} />
      <ColorSlider channel="alpha" value={color} onChange={setColor} />
    </>
  );
}

function Example() {
  let [color, setColor] = React.useState(
    parseColor('hsb(0, 100%, 50%)')
  );
  return (
    <>
      <ColorSlider
        channel="hue"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="saturation"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="brightness"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="alpha"
        value={color}
        onChange={setColor}
      />
    </>
  );
}

function Example() {
  let [
    color,
    setColor
  ] = React.useState(
    parseColor(
      'hsb(0, 100%, 50%)'
    )
  );
  return (
    <>
      <ColorSlider
        channel="hue"
        value={color}
        onChange={
          setColor
        }
      />
      <ColorSlider
        channel="saturation"
        value={color}
        onChange={
          setColor
        }
      />
      <ColorSlider
        channel="brightness"
        value={color}
        onChange={
          setColor
        }
      />
      <ColorSlider
        channel="alpha"
        value={color}
        onChange={
          setColor
        }
      />
    </>
  );
}

Step#

The step prop can be used to make a ColorSlider snap its value to specific increments.

<ColorSlider channel="hue" defaultValue="hsl(0, 100%, 50%)" step={30} />

<ColorSlider
  channel="hue"
  defaultValue="hsl(0, 100%, 50%)"
  step={30}
/>

<ColorSlider
  channel="hue"
  defaultValue="hsl(0, 100%, 50%)"
  step={30}
/>

onChangeEnd#

The onChangeEnd prop can be used to handle when a user stops dragging a color slider, whereas the onChange prop is called as the user drags.

function Example() {
  let [color, setColor] = React.useState(parseColor('#7f007f'));
  return (
    <>
      <ColorSlider channel="red" defaultValue={color} onChangeEnd={setColor} />
      <p>Current color value: {color.toString('hex')}</p>
    </>
  );
}

function Example() {
  let [color, setColor] = React.useState(
    parseColor('#7f007f')
  );
  return (
    <>
      <ColorSlider
        channel="red"
        defaultValue={color}
        onChangeEnd={setColor}
      />
      <p>Current color value: {color.toString('hex')}</p>
    </>
  );
}

function Example() {
  let [
    color,
    setColor
  ] = React.useState(
    parseColor('#7f007f')
  );
  return (
    <>
      <ColorSlider
        channel="red"
        defaultValue={
          color
        }
        onChangeEnd={
          setColor
        }
      />
      <p>
        Current color
        value:{' '}
        {color.toString(
          'hex'
        )}
      </p>
    </>
  );
}

Disabled#

A ColorSlider can be disabled using the isDisabled prop. This prevents the thumb from being focused or dragged. It's up to you to style your color slider to appear disabled accordingly.

<ColorSlider channel="red" defaultValue="#7f007f" isDisabled />

<ColorSlider
  channel="red"
  defaultValue="#7f007f"
  isDisabled
/>

<ColorSlider
  channel="red"
  defaultValue="#7f007f"
  isDisabled
/>

Internationalization#

Labeling#

By default, a localized string for the channel name is used as the aria-label for the ColorSlider. When a custom aria-label or visual label is provided, it should be localized accordingly. To get a localized channel name to use as the visual label, you can use the color.getChannelName method.

Value formatting#

The aria-valuetext of the <input> element is formatted according to the user's locale automatically. If you wish to display this value visually in the <output> element, you can use the color.formatChannelValue method.

RTL#

In right-to-left languages, color sliders should be mirrored. The label should be right aligned, and the value should be left aligned. Ensure that your CSS accounts for this. Positioning of the thumb and dragging behavior is automatically mirrored by useColorSlider.
