ColorSlider

ColorSliders allow users to adjust an individual channel of a color value.

usageimport {ColorSlider} from '@react-spectrum/color'

Example#


<ColorSlider defaultValue="#7f0000" channel="red" />
<ColorSlider defaultValue="#7f0000" channel="red" />
<ColorSlider
  defaultValue="#7f0000"
  channel="red"
/>

Value#


A ColorSlider 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. The channel prop must also be provided to specify which color channel the slider should display. 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.

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

function Example() {
  let [value, setValue] = React.useState(parseColor('hsl(0, 100%, 50%)'));
  return (
    <Flex gap="size-300" wrap>
      <ColorSlider
        label="Hue (uncontrolled)"
        defaultValue="hsl(0, 100%, 50%)"
        channel="hue" />
      <ColorSlider
        label="Hue (controlled)"
        value={value}
        onChange={setValue}
        channel="hue" />
    </Flex>
  );
}
import {parseColor} from '@react-stately/color';

function Example() {
  let [value, setValue] = React.useState(
    parseColor('hsl(0, 100%, 50%)')
  );
  return (
    <Flex gap="size-300" wrap>
      <ColorSlider
        label="Hue (uncontrolled)"
        defaultValue="hsl(0, 100%, 50%)"
        channel="hue"
      />
      <ColorSlider
        label="Hue (controlled)"
        value={value}
        onChange={setValue}
        channel="hue"
      />
    </Flex>
  );
}
import {parseColor} from '@react-stately/color';

function Example() {
  let [value, setValue] =
    React.useState(
      parseColor(
        'hsl(0, 100%, 50%)'
      )
    );
  return (
    <Flex
      gap="size-300"
      wrap
    >
      <ColorSlider
        label="Hue (uncontrolled)"
        defaultValue="hsl(0, 100%, 50%)"
        channel="hue"
      />
      <ColorSlider
        label="Hue (controlled)"
        value={value}
        onChange={setValue}
        channel="hue"
      />
    </Flex>
  );
}

HTML forms#

ColorSlider supports the name prop for integration with HTML forms. The value will be submitted as a number between the minimum and maximum value for the displayed channel.

<ColorSlider
  defaultValue="#7f0000"
  channel="red"
  name="red" />
<ColorSlider
  defaultValue="#7f0000"
  channel="red"
  name="red" />
<ColorSlider
  defaultValue="#7f0000"
  channel="red"
  name="red" />

Labeling#


The ColorSlider's channel name and value are shown above the ColorSlider by default. The label and value label can be hidden by providing label={null} and showValueLabel={false} to the ColorSlider, respectively. In addition, a custom label can be provided via the label prop.

<Flex gap="size-300" wrap alignItems="end">
  <ColorSlider
    channel="saturation"
    defaultValue="hsl(0, 100%, 50%)"
    label={null}
  />
  <ColorSlider
    channel="lightness"
    defaultValue="hsl(0, 100%, 50%)"
    showValueLabel={false}
  />
</Flex>
<Flex gap="size-300" wrap alignItems="end">
  <ColorSlider
    channel="saturation"
    defaultValue="hsl(0, 100%, 50%)"
    label={null}
  />
  <ColorSlider
    channel="lightness"
    defaultValue="hsl(0, 100%, 50%)"
    showValueLabel={false}
  />
</Flex>
<Flex
  gap="size-300"
  wrap
  alignItems="end"
>
  <ColorSlider
    channel="saturation"
    defaultValue="hsl(0, 100%, 50%)"
    label={null}
  />
  <ColorSlider
    channel="lightness"
    defaultValue="hsl(0, 100%, 50%)"
    showValueLabel={false}
  />
</Flex>

Accessibility#

If the ColorSlider's label is hidden, a localized string for the channel name is used as the aria-label by default. The value of the ColorSlider is also automatically localized and provided to the input as aria-valuetext regardless of the value label's visibility. If you provide your own aria-label or aria-labelledby, be sure to localize the string or labeling element appropriately.

Internationalization#

For languages that are read right-to-left (e.g. Hebrew and Arabic), the layout of the ColorSlider is automatically flipped. As mentioned previously, ColorSlider automatically uses the current locale to format the channel and value label.

Events#


ColorSlider supports two events: onChange and onChangeEnd. onChange is triggered whenever the ColorSlider'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 ColorSlider'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>
      <ColorSlider
        value={currentValue}
        channel="hue"
        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>
      <ColorSlider
        value={currentValue}
        channel="hue"
        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>
      <ColorSlider
        value={currentValue}
        channel="hue"
        onChange={setCurrentValue}
        onChangeEnd={setFinalValue}
      />
      <pre>Current value: {currentValue.toString('hsl')}</pre>
      <pre>Final value: {finalValue.toString('hsl')}</pre>
    </div>
  );
}

Creating a color picker#


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.

function Example() {
  let [color, setColor] = React.useState(parseColor('#ff00ff'));

  return (
    <Flex direction="column">
      <ColorSlider channel="red" value={color} onChange={setColor} />
      <ColorSlider channel="green" value={color} onChange={setColor} />
      <ColorSlider channel="blue" value={color} onChange={setColor} />
      <ColorSlider channel="alpha" value={color} onChange={setColor} />
    </Flex>
  );
}
function Example() {
  let [color, setColor] = React.useState(
    parseColor('#ff00ff')
  );

  return (
    <Flex direction="column">
      <ColorSlider
        channel="red"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="green"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="blue"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="alpha"
        value={color}
        onChange={setColor}
      />
    </Flex>
  );
}
function Example() {
  let [color, setColor] =
    React.useState(
      parseColor(
        '#ff00ff'
      )
    );

  return (
    <Flex direction="column">
      <ColorSlider
        channel="red"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="green"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="blue"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="alpha"
        value={color}
        onChange={setColor}
      />
    </Flex>
  );
}

HSLA#

This example shows how to build a similar color picker to the one above, using HSLA colors instead.

function Example() {
  let [color, setColor] = React.useState(parseColor('hsla(0, 100%, 50%, 0.5)'));

  return (
    <Flex direction="column">
      <ColorSlider channel="hue" value={color} onChange={setColor} />
      <ColorSlider channel="saturation" value={color} onChange={setColor} />
      <ColorSlider channel="lightness" value={color} onChange={setColor} />
      <ColorSlider channel="alpha" value={color} onChange={setColor} />
    </Flex>
  );
}
function Example() {
  let [color, setColor] = React.useState(
    parseColor('hsla(0, 100%, 50%, 0.5)')
  );

  return (
    <Flex direction="column">
      <ColorSlider
        channel="hue"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="saturation"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="lightness"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="alpha"
        value={color}
        onChange={setColor}
      />
    </Flex>
  );
}
function Example() {
  let [color, setColor] =
    React.useState(
      parseColor(
        'hsla(0, 100%, 50%, 0.5)'
      )
    );

  return (
    <Flex direction="column">
      <ColorSlider
        channel="hue"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="saturation"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="lightness"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="alpha"
        value={color}
        onChange={setColor}
      />
    </Flex>
  );
}

HSBA#

This example shows how to build an HSBA color picker.

function Example() {
  let [color, setColor] = React.useState(parseColor('hsba(0, 100%, 50%, 0.5)'));
  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('hsba(0, 100%, 50%, 0.5)')
  );
  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(
        'hsba(0, 100%, 50%, 0.5)'
      )
    );
  return (
    <>
      <ColorSlider
        channel="hue"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="saturation"
        value={color}
        onChange={setColor}
      />
      <ColorSlider
        channel="brightness"

    </>
  );
}
