Color Picker

<wa-color-picker>

Stable

Color pickers let users choose a color from a visual palette or by entering a value. They support HEX, RGB, HSL, and HSV formats with optional alpha channel and swatch presets.

<wa-color-picker label="Select a color"></wa-color-picker>

This component works with standard <form> elements. See form controls for form submission and client-side validation.

Examples

Link to This Section

Label

Link to This Section

Use the label attribute to give the color picker an accessible label. For labels that contain HTML, use the label slot instead.

<wa-color-picker label="Brand color"></wa-color-picker>

Hint

Link to This Section

Add a descriptive hint with the hint attribute. For hints that contain HTML, use the hint slot instead.

<wa-color-picker label="Accent" hint="Pick something with enough contrast to read against white."></wa-color-picker>

Initial Value

Link to This Section

Use the value attribute to set a starting color. The value's format follows the format attribute, but any parsable color (including CSS color names) is accepted as input.

<wa-color-picker value="#4a90e2" label="Select a color"></wa-color-picker>

Format

Link to This Section

Set the color picker's format with the format attribute. Valid options are hex, rgb, hsl, and hsv. The input still accepts any parsable format regardless of this setting.

To stop people from cycling through formats themselves, add the without-format-toggle attribute.

<div class="wa-grid" style="--min-column-size: 12ch;">
  <wa-color-picker format="hex" value="#4a90e2" label="Pick a hex color"></wa-color-picker>
  <wa-color-picker format="rgb" value="rgb(80, 227, 194)" label="Pick an RGB color"></wa-color-picker>
  <wa-color-picker format="hsl" value="hsl(290, 87%, 47%)" label="Pick an HSL color"></wa-color-picker>
  <wa-color-picker format="hsv" value="hsv(55, 89%, 97%)" label="Pick an HSV color"></wa-color-picker>
</div>

Opacity

Link to This Section

Use the opacity attribute to add an opacity slider. With opacity enabled, the value is shown as HEXA, RGBA, HSLA, or HSVA to match the format.

<wa-color-picker value="#f5a623ff" opacity label="Select a color"></wa-color-picker>

Uppercase Values

Link to This Section

By default, values are lowercase. Add the uppercase attribute to display them in uppercase instead.

<wa-color-picker value="#4a90e2" uppercase label="Select a color"></wa-color-picker>

Swatches

Link to This Section

Use the swatches attribute to offer preset colors. Any format the picker can parse works (including CSS color names), and each value must be separated by a semicolon (;).

<wa-color-picker
  label="Select a color"
  swatches="
    #d0021b; #f5a623; #f8e71c; #8b572a; #7ed321; #417505; #bd10e0; #9013fe;
    #4a90e2; #50e3c2; #b8e986; #000; #444; #888; #ccc; #fff;
  "
></wa-color-picker>

To give swatches accessible names, set the swatches property in JavaScript to an array of { color, label } objects — each label becomes that swatch's accessible name instead of the raw color value. (Their appearance is identical, so this isn't a live example.)

const picker = document.querySelector('wa-color-picker');
picker.swatches = [
  { color: '#d0021b', label: 'Red' },
  { color: '#f5a623', label: 'Orange' },
  { color: '#417505', label: 'Green' },
  { color: '#4a90e2', label: 'Blue' },
];

Placement

Link to This Section

Set the placement attribute to control where the dropdown opens. The actual position may shift to keep the panel inside the viewport.

<div class="wa-cluster wa-align-items-baseline">
  <wa-color-picker placement="top-start" label="Select a color"></wa-color-picker>
  <wa-color-picker placement="bottom-end" label="Select a color"></wa-color-picker>
  <wa-color-picker placement="right" label="Select a color"></wa-color-picker>
  <wa-color-picker placement="left" label="Select a color"></wa-color-picker>
</div>

Size

Link to This Section

Use the size attribute to change the color picker's trigger size.

<div class="wa-cluster wa-align-items-baseline">
  <wa-color-picker size="xs" label="Extra small"></wa-color-picker>
  <wa-color-picker size="s" label="Small"></wa-color-picker>
  <wa-color-picker size="m" label="Medium"></wa-color-picker>
  <wa-color-picker size="l" label="Large"></wa-color-picker>
  <wa-color-picker size="xl" label="Extra large"></wa-color-picker>
</div>

Disabled

Link to This Section

Use the disabled attribute to disable a color picker.

<wa-color-picker disabled label="Select a color"></wa-color-picker>

Applying the Selected Color

Link to This Section

The color picker emits an input event as the user picks, so you can apply the chosen color to your UI in real time. Here, changing the color themes a preview card.

Brand preview

Pick a color to theme this card in real time.

<div class="color-apply-demo">
  <div class="color-apply-preview">
    <wa-icon name="palette"></wa-icon>
    <div>
      <strong>Brand preview</strong>
      <p>Pick a color to theme this card in real time.</p>
    </div>
  </div>

  <wa-divider></wa-divider>

  <wa-color-picker label="Accent color" value="#6e40c9"></wa-color-picker>
</div>

<script>
  const demo = document.querySelector('.color-apply-demo');
  const picker = demo.querySelector('wa-color-picker');
  const preview = demo.querySelector('.color-apply-preview');

  picker.addEventListener('input', () => {
    preview.style.setProperty('--accent', picker.value);
  });
</script>

<style>
  .color-apply-demo .color-apply-preview {
    --accent: #6e40c9;
    display: flex;
    align-items: center;
    gap: var(--wa-space-m);
    margin-block-end: 1rem;
    padding: var(--wa-space-l);
    border-radius: var(--wa-border-radius-l);
    border-inline-start: 4px solid var(--accent);
    background-color: color-mix(in srgb, var(--accent) 12%, transparent);
  }

  .color-apply-demo .color-apply-preview wa-icon {
    color: var(--accent);
    font-size: 1.5rem;
  }

  .color-apply-demo .color-apply-preview strong {
    color: var(--accent);
  }

  .color-apply-demo .color-apply-preview p {
    margin: 0.25rem 0 0;
  }
</style>

Attributes & Properties

Link to This Section

Learn more about attributes and properties.

Name	Description	Reflects
`defaultValue` `value`	The default value of the form control. Primarily used for resetting the form control. Type `string \| null`
`disabled` `disabled`	Disables the color picker. Type `boolean` Default `false`
`form`	By default, form controls are associated with the nearest containing `<form>` element. This attribute allows you to place the form control outside of a form and associate it with the form that has this `id`. The form must be in the same document or shadow root for this to work. Type `HTMLFormElement \| null`
`format` `format`	The format to use. If opacity is enabled, these will translate to HEXA, RGBA, HSLA, and HSVA respectively. The color picker will accept user input in any format (including CSS color names) and convert it to the desired format. Type `'hex' \| 'rgb' \| 'hsl' \| 'hsv'` Default `'hex'`
`hint` `hint`	The color picker's hint. If you need to display HTML, use the `hint` slot instead. Type `string` Default `''`
`label` `label`	The color picker's label. This will not be displayed, but it will be announced by assistive devices. If you need to display HTML, you can use the `label` slot` instead. Type `string` Default `''`
`name` `name`	The name of the form control, submitted as a name/value pair with form data. Type `string \| null` Default `null`
`opacity` `opacity`	Shows the opacity slider. Enabling this will cause the formatted value to be HEXA, RGBA, or HSLA. Type `boolean` Default `false`
`open` `open`	Indicates whether or not the popup is open. You can toggle this attribute to show and hide the popup, or you can use the `show()` and `hide()` methods and this attribute will reflect the popup's open state. Type `boolean` Default `false`
`placement` `placement`	The preferred placement of the color picker's popup. Note that the actual placement will vary as configured to keep the panel inside of the viewport. Type `'top' \| 'top-start' \| 'top-end' \| 'bottom' \| 'bottom-start' \| 'bottom-end' \| 'right' \| 'right-start' \| 'right-end' \| 'left' \| 'left-start' \| 'left-end'` Default `'bottom-start'`
`required` `required`	Makes the color picker a required field. Type `boolean` Default `false`
`size` `size`	Determines the size of the color picker's trigger Type `'xs' \| 's' \| 'm' \| 'l' \| 'xl' \| 'small' \| 'medium' \| 'large'` Default `'m'`
`swatches` `swatches`	One or more predefined color swatches to display as presets in the color picker. Can include any format the color picker can parse, including HEX(A), RGB(A), HSL(A), HSV(A), and CSS color names. Each color must be separated by a semicolon (`;`). Alternatively, you can pass an array of color values or an array of `{ color, label }` objects to this property using JavaScript. When using objects with labels, the label will be used for the swatch's accessible name instead of the raw color value. Type `string \| string[] \| WaColorPickerSwatch[]` Default `''`
`uppercase` `uppercase`	By default, values are lowercase. With this attribute, values will be uppercase instead. Type `boolean` Default `false`
`validationTarget`	Override this to change where constraint validation popups are anchored. Type `undefined \| HTMLElement`
`validators`	Validators are static because they have `observedAttributes`, essentially attributes to "watch" for changes. Whenever these attributes change, we want to be notified and update the validator. Type `Validator[]` Default `[]`
`value`	The current value of the color picker. The value's format will vary based the `format` attribute. To get the value in a specific format, use the `getFormattedValue()` method. The value is submitted as a name/value pair with form data.
`withHint` `with-hint`	Only required for SSR. Set to `true` if you're slotting in a `hint` element so the server-rendered markup includes the hint before the component hydrates on the client. Type `boolean` Default `false`
`withLabel` `with-label`	Only required for SSR. Set to `true` if you're slotting in a `label` element so the server-rendered markup includes the label before the component hydrates on the client. Type `boolean` Default `false`
`withoutFormatToggle` `without-format-toggle`	Removes the button that lets users toggle between format. Type `boolean` Default `false`

`blur()`	Removes focus from the color picker.
`focus()`	Sets focus on the color picker.	`options: FocusOptions`
`formStateRestoreCallback()`	Called when the browser is trying to restore element’s state to state in which case reason is "restore", or when the browser is trying to fulfill autofill on behalf of user in which case reason is "autocomplete". In the case of "restore", state is a string, File, or FormData object previously set as the second argument to setFormValue.	`state: string \| File \| FormData \| null, reason: 'autocomplete' \| 'restore'`
