usage | import {ColorField} from '@react-spectrum/color' |
Example#
<ColorField label="Primary Color" />
<ColorField label="Primary Color" />
<ColorField label="Primary Color" />
Value#
A ColorField's value
is empty by default, but an initial, uncontrolled, value can be provided using the defaultValue
prop.
Alternatively, a controlled value can be provided using the value
prop. Valid values are hexadecimal color codes.
The parseColor
function is used to parse the initial color
from a hex value, stored in state.
import {parseColor} from '@react-stately/color';
function Example() {
let [value, setValue] = React.useState(parseColor('#e73623'));
return (
<Flex gap="size-150" wrap>
<ColorField
label="Primary Color (Uncontrolled)"
defaultValue="#e21" />
<ColorField
label="Primary Color (Controlled)"
value={value}
onChange={setValue} />
</Flex>
);
}
import {parseColor} from '@react-stately/color';
function Example() {
let [value, setValue] = React.useState(
parseColor('#e73623')
);
return (
<Flex gap="size-150" wrap>
<ColorField
label="Primary Color (Uncontrolled)"
defaultValue="#e21"
/>
<ColorField
label="Primary Color (Controlled)"
value={value}
onChange={setValue}
/>
</Flex>
);
}
import {parseColor} from '@react-stately/color';
function Example() {
let [value, setValue] =
React.useState(
parseColor(
'#e73623'
)
);
return (
<Flex
gap="size-150"
wrap
>
<ColorField
label="Primary Color (Uncontrolled)"
defaultValue="#e21"
/>
<ColorField
label="Primary Color (Controlled)"
value={value}
onChange={setValue}
/>
</Flex>
);
}
Labeling#
A visual label should be provided for the ColorField using the label
prop. If the ColorField is required, the isRequired
and
necessityIndicator
props can be used to show a required state.
<Flex gap="size-150" wrap>
<ColorField label="Primary Color" />
<ColorField label="Primary Color" isRequired />
<ColorField label="Primary Color" isRequired necessityIndicator="label" />
<ColorField label="Primary Color" necessityIndicator="label" />
</Flex>
<Flex gap="size-150" wrap>
<ColorField label="Primary Color" />
<ColorField label="Primary Color" isRequired />
<ColorField
label="Primary Color"
isRequired
necessityIndicator="label"
/>
<ColorField
label="Primary Color"
necessityIndicator="label"
/>
</Flex>
<Flex
gap="size-150"
wrap
>
<ColorField label="Primary Color" />
<ColorField
label="Primary Color"
isRequired
/>
<ColorField
label="Primary Color"
isRequired
necessityIndicator="label"
/>
<ColorField
label="Primary Color"
necessityIndicator="label"
/>
</Flex>
Accessibility#
If a visible label isn't specified, an aria-label
must be provided to the ColorField for
accessibility. If the field is labeled by a separate element, an aria-labelledby
prop must be provided using
the id
of the labeling element instead.
Internationalization#
In order to internationalize a ColorField, a localized string should be passed to the label
or aria-label
prop.
When the necessityIndicator
prop is set to "label"
, a localized string will be provided for "(required)"
or "(optional)"
automatically.
Validation#
ColorField can display a validation state to communicate to the user whether the current value is valid or invalid.
Implement your own validation logic in your app and pass either "valid"
or "invalid"
to the ColorField via the validationState
prop.
The example below illustrates how one would validate if the user has entered a red color. In it,
the parseColor
function is used to parse the
initial color from a hexadecimal string so that value
's type remains consistent.
function Example() {
let [value, setValue] = React.useState(parseColor('#e73623'));
let isValid = React.useMemo(() => {
return value && value.red && value.red > value.green &&
value.red > value.blue;
}, [value]);
return (
<ColorField
validationState={isValid ? 'valid' : 'invalid'}
value={value}
onChange={setValue}
label="Red colors"
/>
);
}
function Example() {
let [value, setValue] = React.useState(
parseColor('#e73623')
);
let isValid = React.useMemo(() => {
return value && value.red && value.red > value.green &&
value.red > value.blue;
}, [value]);
return (
<ColorField
validationState={isValid ? 'valid' : 'invalid'}
value={value}
onChange={setValue}
label="Red colors"
/>
);
}
function Example() {
let [value, setValue] =
React.useState(
parseColor(
'#e73623'
)
);
let isValid = React
.useMemo(() => {
return value &&
value.red &&
value.red >
value.green &&
value.red >
value.blue;
}, [value]);
return (
<ColorField
validationState={isValid
? 'valid'
: 'invalid'}
value={value}
onChange={setValue}
label="Red colors"
/>
);
}

Visual options#
Quiet#
<ColorField label="Primary Color" isQuiet />
<ColorField label="Primary Color" isQuiet />
<ColorField
label="Primary Color"
isQuiet

Disabled#
<ColorField label="Primary Color" isDisabled defaultValue="#e73623" />
<ColorField
label="Primary Color"
isDisabled
defaultValue="#e73623"
/>
<ColorField
label="Primary Color"
isDisabled
defaultValue="#e73623"
/>
Read only#
The isReadOnly
boolean prop makes the ColorField's text content immutable. Unlike isDisabled
, the ColorField remains focusable
and the contents can still be copied. See the MDN docs for more information.
<ColorField label="Primary Color" isReadOnly defaultValue="#e73623" />
<ColorField
label="Primary Color"
isReadOnly
defaultValue="#e73623"
/>
<ColorField
label="Primary Color"
isReadOnly
defaultValue="#e73623"
/>
Label alignment and position#
By default, the label is positioned above the ColorField. The labelPosition
prop can be used to position the label to the side.
The labelAlign
prop can be used to align the label as "start" or "end". For left-to-right (LTR) languages, "start" refers to the
left most edge of the ColorField and "end" refers to the right most edge. For right-to-left (RTL) languages, this is flipped.
<ColorField label="Primary Color" labelPosition="side" labelAlign="end" />
<ColorField
label="Primary Color"
labelPosition="side"
labelAlign="end"
/>
<ColorField
label="Primary Color"
labelPosition="side"
labelAlign="end"
/>
Help text#
Both a description and an error message can be supplied to a ColorField. The description is always visible unless the validationState
is “invalid” and an error message is provided. The error message can be used to help the user fix their input quickly and should be specific to the detected error. All strings should be localized.

let [value, setValue] = React.useState(parseColor('#e73623'));
