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 field for editing a hex value or individual color channel. ColorField
helps achieve accessible
color fields that can be styled as needed.
- Interactions – Supports entering a value using a keyboard, incrementing and decrementing with the arrow keys, and adjusting the value with the scroll wheel.
- Validation – Keyboard input is validated as the user types so that only valid characters are accepted. Custom client and server-side validation is also supported.
- Accessible – Follows the spinbutton ARIA pattern. Extensively tested across many devices and assistive technologies to ensure announcements and behaviors are consistent.
Anatomy#
A color field consists of an input element and a label. It also supports optional description and error message elements, which can be used to provide more context about the field, and any validation messages.
import {ColorField, FieldError, Input, Label, Text} from 'react-aria-components';
<ColorField>
<Label />
<Input />
<Text slot="description" />
<FieldError />
</ColorField>
import {
ColorField,
FieldError,
Input,
Label,
Text
} from 'react-aria-components';
<ColorField>
<Label />
<Input />
<Text slot="description" />
<FieldError />
</ColorField>
import {
ColorField,
FieldError,
Input,
Label,
Text
} from 'react-aria-components';
<ColorField>
<Label />
<Input />
<Text slot="description" />
<FieldError />
</ColorField>
If there is no visual label, an aria-label
or aria-labelledby
prop must be passed instead
to identify the element to screen readers.
Concepts#
ColorField
makes use of the following concepts:
Composed components#
A ColorField
uses the following components, which may also be used standalone or reused in other components.
Starter kits#
To help kick-start your project, we offer starter kits that include example implementations of all React Aria components with various styling solutions. All components are fully styled, including support for dark mode, high contrast mode, and all UI states. Each starter comes with a pre-configured Storybook that you can experiment with, or use as a starting point for your own component library.
Reusable wrappers#
If you will use a ColorField in multiple places in your app, you can wrap all of the pieces into a reusable component. This way, the DOM structure, styling code, and other logic are defined in a single place and reused everywhere to ensure consistency.
This example wraps ColorField
and all of its children together into a single component which accepts a label
prop, which is passed to the right place. It also shows how to use the description
slot to render help text, and FieldError
component to render validation errors.
import type {ColorFieldProps, ValidationResult} from 'react-aria-components';
import {FieldError, Text} from 'react-aria-components';
interface MyColorFieldProps extends ColorFieldProps {
label?: string;
description?: string;
errorMessage?: string | ((validation: ValidationResult) => string);
}
export function MyColorField(
{ label, description, errorMessage, ...props }: MyColorFieldProps
) {
return (
<ColorField {...props}>
{label && <Label>{label}</Label>}
<Input />
{description && <Text slot="description">{description}</Text>}
<FieldError>{errorMessage}</FieldError>
</ColorField>
);
}
<MyColorField label="Color" />
import type {
ColorFieldProps,
ValidationResult
} from 'react-aria-components';
import {FieldError, Text} from 'react-aria-components';
interface MyColorFieldProps extends ColorFieldProps {
label?: string;
description?: string;
errorMessage?:
| string
| ((validation: ValidationResult) => string);
}
export function MyColorField(
{ label, description, errorMessage, ...props }:
MyColorFieldProps
) {
return (
<ColorField {...props}>
{label && <Label>{label}</Label>}
<Input />
{description && (
<Text slot="description">{description}</Text>
)}
<FieldError>{errorMessage}</FieldError>
</ColorField>
);
}
<MyColorField label="Color" />
import type {
ColorFieldProps,
ValidationResult
} from 'react-aria-components';
import {
FieldError,
Text
} from 'react-aria-components';
interface MyColorFieldProps
extends
ColorFieldProps {
label?: string;
description?: string;
errorMessage?:
| string
| ((
validation:
ValidationResult
) => string);
}
export function MyColorField(
{
label,
description,
errorMessage,
...props
}: MyColorFieldProps
) {
return (
<ColorField
{...props}
>
{label && (
<Label>
{label}
</Label>
)}
<Input />
{description && (
<Text slot="description">
{description}
</Text>
)}
<FieldError>
{errorMessage}
</FieldError>
</ColorField>
);
}
<MyColorField label="Color" />
Value#
A ColorField accepts either a color string or Color
object as a value.
Uncontrolled#
By default, ColorField
is uncontrolled. You can set a default value using the defaultValue
prop.
<MyColorField label="Color" defaultValue="#7f007f" />
<MyColorField label="Color" defaultValue="#7f007f" />
<MyColorField
label="Color"
defaultValue="#7f007f"
/>
Controlled#
A ColorField
can be made controlled. The parseColor
function is used to parse the initial color from a hex string, stored in state. The value
and onChange
props
are used to update the value in state when the edits the value.
import {parseColor} from 'react-aria-components';
function Example() {
let [color, setColor] = React.useState(parseColor('#7f007f'));
return (
<>
<MyColorField label="Color" value={color} onChange={setColor} />
<p>Current color value: {color?.toString('hex')}</p>
</>
);
}
import {parseColor} from 'react-aria-components';
function Example() {
let [color, setColor] = React.useState(
parseColor('#7f007f')
);
return (
<>
<MyColorField
label="Color"
value={color}
onChange={setColor}
/>
<p>Current color value: {color?.toString('hex')}</p>
</>
);
}
import {parseColor} from 'react-aria-components';
function Example() {
let [color, setColor] =
React.useState(
parseColor(
'#7f007f'
)
);
return (
<>
<MyColorField
label="Color"
value={color}
onChange={setColor}
/>
<p>
Current color
value:{' '}
{color?.toString(
'hex'
)}
</p>
</>
);
}
HTML forms#
ColorField supports the name
prop for integration with HTML forms. The value will be submitted to the server as a hex color string. When a channel
prop is provided, the value will be submitted as a number instead.
<MyColorField label="Color" name="color" />
<MyColorField label="Color" name="color" />
<MyColorField
label="Color"
name="color"
/>
Color channel#
By default, ColorField allows the user to edit the color as a hex value. When the colorSpace
and channel
props are provided, ColorField displays the value for that channel formatted as a number instead. Rendering multiple ColorFields together can allow a user to edit a color.
function Example() {
let [color, setColor] = React.useState(parseColor('#7f007f'));
return (
<>
<div style={{ display: 'flex', gap: 8 }}>
<MyColorField
label="Hue"
value={color}
onChange={setColor}
colorSpace="hsl"
channel="hue"
/>
<MyColorField
label="Saturation"
value={color}
onChange={setColor}
colorSpace="hsl"
channel="saturation"
/>
<MyColorField
label="Lightness"
value={color}
onChange={setColor}
colorSpace="hsl"
channel="lightness"
/>
</div>
<p>Current color value: {color?.toString('hex')}</p>
</>
);
}
function Example() {
let [color, setColor] = React.useState(
parseColor('#7f007f')
);
return (
<>
<div style={{ display: 'flex', gap: 8 }}>
<MyColorField
label="Hue"
value={color}
onChange={setColor}
colorSpace="hsl"
channel="hue"
/>
<MyColorField
label="Saturation"
value={color}
onChange={setColor}
colorSpace="hsl"
channel="saturation"
/>
<MyColorField
label="Lightness"
value={color}
onChange={setColor}
colorSpace="hsl"
channel="lightness"
/>
</div>
<p>Current color value: {color?.toString('hex')}</p>
</>
);
}
function Example() {
let [color, setColor] =
React.useState(
parseColor(
'#7f007f'
)
);
return (
<>
<div
style={{
display:
'flex',
gap: 8
}}
>
<MyColorField
label="Hue"
value={color}
onChange={setColor}
colorSpace="hsl"
channel="hue"
/>
<MyColorField
label="Saturation"
value={color}
onChange={setColor}
colorSpace="hsl"
channel="saturation"
/>
<MyColorField
label="Lightness"
value={color}
onChange={setColor}
colorSpace="hsl"
channel="lightness"
/>
</div>
<p>
Current color
value:{' '}
{color?.toString(
'hex'
)}
</p>
</>
);
}
Validation#
ColorField supports the isRequired
prop to ensure the user enters a value, as well as custom validation functions, realtime validation, and server-side validation. It can also be integrated with other form libraries. See the Forms guide to learn more.
To display validation errors, add a <FieldError>
element as a child of the ColorField. This allows you to render error messages from all of the above sources with consistent custom styles.
import {Form, FieldError, Button} from 'react-aria-components';
<Form>
<ColorField name="color" isRequired> <Label>Color</Label>
<Input />
<FieldError /> </ColorField>
<Button type="submit">Submit</Button>
</Form>
import {
Button,
FieldError,
Form
} from 'react-aria-components';
<Form>
<ColorField name="color" isRequired> <Label>Color</Label>
<Input />
<FieldError /> </ColorField>
<Button type="submit">Submit</Button>
</Form>
import {
Button,
FieldError,
Form
} from 'react-aria-components';
<Form>
<ColorField
name="color"
isRequired
> <Label>
Color
</Label>
<Input />
<FieldError /> </ColorField>
<Button type="submit">
Submit
</Button>
</Form>

displays default validation messages provided by the browser. See Customizing error messages in the Forms guide to learn how to provide your own custom errors.
Description#
The description
slot can be used to associate additional help text with a color field.
<ColorField>
<Label>Color</Label>
<Input />
<Text slot="description">Enter a background color.</Text></ColorField>
<ColorField>
<Label>Color</Label>

prop can be used prevent the user from editing the value of the color field.
<MyColorField label="Disabled" defaultValue="#7f007f" isDisabled />

defaultValue="#7f007f"
isDisabled

Read only#
The isReadOnly
prop makes the ColorField's value immutable. Unlike isDisabled
, the ColorField remains focusable
and the contents can still be copied. See the MDN docs for more information.
<MyColorField label="Read only" isReadOnly value="#7f007f" />

Styling#
React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin className
attribute which can be targeted using CSS selectors. These follow the react-aria-ComponentName
naming convention.
.react-aria-ColorField {
/* ... */
}
.react-aria-ColorField {
/* ... */
}
.react-aria-ColorField {
/* ... */
}
A custom className
can also be specified on any component. This overrides the default className
provided by React Aria with your own.
<ColorField className="my-color-field">
{/* ... */}
</ColorField>
<ColorField className="my-color-field">
{/* ... */}
</ColorField>
<ColorField className="my-color-field">
{/* ... */}
</ColorField>
In addition, some components support multiple UI states (e.g. focused, placeholder, readonly, etc.). React Aria components expose states using data attributes, which you can target in CSS selectors. For example:
.react-aria-Input[data-focus-visible] {
/* ... */
}
.react-aria-Input[data-focus-visible] {
/* ... */
}
.react-aria-Input[data-focus-visible] {
/* ... */
}
The className
and style
props also accept functions which receive states for styling. This lets you dynamically determine the classes or styles to apply, which is useful when using utility CSS libraries like Tailwind.
<Input
className={({ isFocused }) =>
isFocused ? 'border-blue-500' : 'border-gray-600'}
/>
<Input
className={({ isFocused }) =>
isFocused ? 'border-blue-500' : 'border-gray-600'}
/>
<Input
className={(
{ isFocused }
) =>
isFocused
? 'border-blue-500'
: 'border-gray-600'}
/>
The states, selectors, and render props for each component used in a ColorField
are documented below.
ColorField#
A ColorField
can be targeted with the .react-aria-ColorField
CSS selector, or by overriding with a custom className
. It supports the following states:
Name | CSS Selector | Description |
isDisabled | [data-disabled] | Whether the color field is disabled. |
isInvalid | [data-invalid] | Whether the color field is invalid. |
channel | [data-channel="hex | hue | saturation | ..."] | The color channel that this field edits, or "hex" if no channel prop is set. |
state | — | State of the color field. |
Label#
A Label
can be targeted with the .react-aria-Label
CSS selector, or by overriding with a custom className
.
Input#
An Input
can be targeted with the .react-aria-Input
CSS selector, or by overriding with a custom className
. It supports the following states:
Name | CSS Selector | Description |
isHovered | [data-hovered] | Whether the input is currently hovered with a mouse. |
isFocused | [data-focused] | Whether the input is focused, either via a mouse or keyboard. |
isFocusVisible | [data-focus-visible] | Whether the input is keyboard focused. |
isDisabled | [data-disabled] | Whether the input is disabled. |
isInvalid | [data-invalid] | Whether the input is invalid. |
Text#
The help text elements within a ColorField
can be targeted with the [slot=description]
and [slot=errorMessage]
CSS selectors, or by adding a custom className
.
FieldError#
A FieldError
can be targeted with the .react-aria-FieldError
CSS selector, or by overriding with a custom className
. It supports the following render props:
Name | Description |
isInvalid | Whether the input value is invalid. |
validationErrors | The current error messages for the input if it is invalid, otherwise an empty array. |
validationDetails | The native validation details for the input. |
Advanced customization#
Composition#
If you need to customize one of the components within a ColorField
, such as Label
or Input
, in many cases you can create a wrapper component. This lets you customize the props passed to the component.
function MyInput(props) {
return <Input {...props} className="my-input" />
}
function MyInput(props) {
return <Input {...props} className="my-input" />
}
function MyInput(props) {
return (
<Input
{...props}
className="my-input"
/>
);
}
Contexts#
All React Aria Components export a corresponding context that can be used to send props to them from a parent element. This enables you to build your own compositional APIs similar to those found in React Aria Components itself. You can send any prop or ref via context that you could pass to the corresponding component. The local props and ref on the component are merged with the ones passed via context, with the local props taking precedence (following the rules documented in mergeProps).
Component | Context | Props | Ref |
ColorField | ColorFieldContext | ColorFieldProps | HTMLDivElement |
This example shows a FieldGroup
component that renders a group of color fields with a title. The entire group can be marked as read only via the isReadOnly
prop, which is passed to all child color fields via the ColorFieldContext
provider.
import {ColorFieldContext} from 'react-aria-components';
interface FieldGroupProps {
title?: string,
children?: React.ReactNode,
isReadOnly?: boolean
}
function FieldGroup({title, children, isReadOnly}: FieldGroupProps) {
return (
<fieldset>
<legend>{title}</legend>
<ColorFieldContext.Provider value={{isReadOnly}}> {children}
</ColorFieldContext.Provider>
</fieldset>
);
}
<FieldGroup title="Colors" isReadOnly>
<MyColorField label="Background" defaultValue="#fff" />
<MyColorField label="Foreground" defaultValue="#000" />
</FieldGroup>
import {ColorFieldContext} from 'react-aria-components';
interface FieldGroupProps {
title?: string;
children?: React.ReactNode;
isReadOnly?: boolean;
}
function FieldGroup(
{ title, children, isReadOnly }: FieldGroupProps
) {
return (
<fieldset>
<legend>{title}</legend>
<ColorFieldContext.Provider value={{ isReadOnly }}> {children}
</ColorFieldContext.Provider>
</fieldset>
);
}
<FieldGroup title="Colors" isReadOnly>
<MyColorField label="Background" defaultValue="#fff" />

Custom children#
ColorField passes props to its child components, such as the label and input, via their associated contexts. These contexts are exported so you can also consume them in your own custom components. This enables you to reuse existing components from your app or component library together with React Aria Components.
Component | Context | Props | Ref |
Label | LabelContext | LabelProps | HTMLLabelElement |
Input | InputContext | InputProps | HTMLInputElement |
Text | TextContext | TextProps | HTMLElement |
This example consumes from LabelContext
in an existing styled label component to make it compatible with React Aria Components. The useContextProps
hook merges the local props and ref with the ones provided via context by ColorField.
import type {LabelProps} from 'react-aria-components';
import {LabelContext, useContextProps} from 'react-aria-components';
const MyCustomLabel = React.forwardRef(
(props: LabelProps, ref: React.ForwardedRef<HTMLLabelElement>) => {
// Merge the local props and ref with the ones provided via context.
[props, ref] = useContextProps(props, ref, LabelContext);
// ... your existing Label component
return <label {...props} ref={ref} />;
}
);
import type {LabelProps} from 'react-aria-components';
import {
LabelContext,
useContextProps
} from 'react-aria-components';
const MyCustomLabel = React.forwardRef(
(
props: LabelProps,
ref: React.ForwardedRef<HTMLLabelElement>
) => {
// Merge the local props and ref with the ones provided via context.
[props, ref] = useContextProps(
props,
ref,
LabelContext
);
// ... your existing Label component
return <label {...props} ref={ref} />;
}
);
import type {LabelProps} from 'react-aria-components';
import {
LabelContext,
useContextProps
} from 'react-aria-components';
const MyCustomLabel =
React.forwardRef(
(
props: LabelProps,
ref:
React.ForwardedRef<
HTMLLabelElement
>
) => {
// Merge the local props and ref with the ones provided via context.
[props, ref] =
useContextProps(
props,
ref,
LabelContext
);
// ... your existing Label component
return (
<label
{...props}
ref={ref}
/>
);
}
);
Now you can use MyCustomLabel
within a ColorField
, in place of the builtin React Aria Components Label
.
<ColorField>
<MyCustomLabel>Value</MyCustomLabel> <Input />
</ColorField>
<ColorField>
<MyCustomLabel>Value</MyCustomLabel> <Input />
</ColorField>
<ColorField>
<MyCustomLabel>
Value
</MyCustomLabel> <Input />
</ColorField>
State#
ColorField provides a ColorFieldState
object to its children via ColorFieldStateContext
. This can be used to access and manipulate the ColorField's state.
Hooks#
If you need to customize things even further, such as accessing internal state or customizing DOM structure, you can drop down to the lower level Hook-based API. See useColorField for more details.
