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

Testing#
The ColorSlider 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.
