Color Picker

The color picker is an input widget used to select a color value from a predefined list or a color area.

This component builds on top of the native <input type=color> experience and provides a more customizable and consistent user experience.

Installation

To use the color picker machine in your project, run the following command in your command line:

npm install @zag-js/color-picker @zag-js/react
# or
yarn add @zag-js/color-picker @zag-js/react

npm install @zag-js/color-picker @zag-js/solid
# or
yarn add @zag-js/color-picker @zag-js/solid

npm install @zag-js/color-picker @zag-js/vue
# or
yarn add @zag-js/color-picker @zag-js/vue

npm install @zag-js/color-picker @zag-js/svelte
# or
yarn add @zag-js/color-picker @zag-js/svelte

This command will install the framework agnostic color picker logic and the reactive utilities for your framework of choice.

Anatomy

To set up the color picker correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Usage

First, import the color picker package into your project

import * as colorPicker from "@zag-js/color-picker"

The color picker package exports these functions:

machine — The state machine logic for the color picker widget.
connect — The function that translates the machine's state to JSX attributes and event handlers.
parse - The function that parses a color string to an Color object.

Next, import the required hooks and functions for your framework and use the color picker machine in your project 🔥

import * as colorPicker from "@zag-js/color-picker"
import { normalizeProps, useMachine } from "@zag-js/react"
import { useId } from "react"

function ColorPicker() {
  const [state, send] = useMachine(
    colorPicker.machine({
      id: useId(),
      value: colorPicker.parse("hsl(0, 100%, 50%)"),
    }),
  )

  const api = colorPicker.connect(state, send, normalizeProps)

  return (
    <div {...api.getRootProps()}>
      <label {...api.getLabelProps()}>Select Color: {api.valueAsString}</label>

      <input {...api.getHiddenInputProps()} />

      <div {...api.getControlProps()}>
        <button {...api.getTriggerProps()}>
          <div {...api.getTransparencyGridProps({ size: "10px" })} />
          <div {...api.getSwatchProps({ value: api.value })} />
        </button>
        <input {...api.getChannelInputProps({ channel: "hex" })} />
        <input {...api.getChannelInputProps({ channel: "alpha" })} />
      </div>

      <div {...api.getPositionerProps()}>
        <div {...api.getContentProps()}>
          <div {...api.getAreaProps()}>

            <div {...api.getTransparencyGridProps({ size: "12px" })} />
            <div {...api.getChannelSliderTrackProps({ channel: "alpha" })} />

Setting the initial value

To set the initial value of the color picker, use the value context property.

const [current, send] = useMachine(
  colorPicker.machine({
    value: colorPicker.parse("#ff0000"),
  }),
)

Listening for change events

When the user selects a color using the color picker, the onValueChange and onValueChangeEnd events will be fired.

onValueChange — Fires in sync as the user selects a color
onValueChangeEnd — Fires when the user stops selecting a color (useful for debounced updates)

const [current, send] = useMachine(
  colorPicker.machine({
    onValueChange: (details) => {
      // details => { value: Color, valueAsString: string }
    },
    onValueChangeEnd: (details) => {
      // details => { value: Color, valueAsString: string }
    },
  }),
)

When using the onValueChange method in React.js, you might need to use the flushSync method from react-dom to ensure the value is updated in sync

Using a custom color format

By default, the color picker's output format is rgba. You can change this format to either hsla or hsba by using the format context property.

When this property is set, the value and valueAsString properties of the onValueChange event will be updated to reflect the new format.

const [current, send] = useMachine(
  colorPicker.machine({
    format: "hsla",
    onValueChange: (details) => {
      // details => { value: HSLAColor, valueAsString: string }
    },
  }),
)

Showing color presets

Adding color presets in form of swatches can help users pick colors faster. To support this, use the getSwatchTriggerProps(...) and getSwatchProps(...) to get the props needed to show the swatches buttons.

const ColorPicker = () => {
  const [state, send] = useMachine(
    colorPicker.machine({
      id: useId(),
      value: colorPicker.parse("hsl(0, 100%, 50%)"),
    }),
  )

  const api = colorPicker.connect(state, send, normalizeProps)

  const presets = ["#ff0000", "#00ff00", "#0000ff"]

  return (
    <div {...api.getRootProps()}>
      {/* ... */}
      <div {...api.getPositionerProps()}>
        <div {...api.getContentProps()}>
          <div {...api.getSwatchGroupProps()}>
            {presets.map((preset) => (
              <button
                key={preset}
                {...api.getSwatchTriggerProps({ value: preset })}
              >
                <div style={{ position: "relative" }}>
                  <div {...api.getTransparencyGridProps({ size: "4px" })} />
                  <div {...api.getSwatchProps({ value: preset })} />
                </div>
              </button>
            ))}

  const [state, send] = useMachine(
    colorPicker.machine({
      id: createUniqueId(),
      value: colorPicker.parse("hsl(0, 100%, 50%)"),
    }),
  )

  const api = createMemo(() => colorPicker.connect(state, send, normalizeProps))

  const presets = ["#ff0000", "#00ff00", "#0000ff"]

    <div {...api().getRootProps()}>

Disabling the color picker

To disable user interactions with the color picker, set the disabled context property to true.

const [current, send] = useMachine(
  colorPicker.machine({
    disabled: true,
  }),
)

Controlling the open and closed state

To control the open and closed state of the color picker, use the open and onOpenChange context properties.

const [current, send] = useMachine(
  colorPicker.machine({
    open: true,
    onOpenChange: (details) => {
      // details => { open: boolean }
    },
  }),
)

You can also leverage the api.setOpen(...) method to control the open and closed state of the color picker.

Controlling individual color channel

In some cases, you may want to allow users to control the values of each color channel individually. You can do this using an input element or a slider element, or both.

To support this, use the getChannelInputProps(...) to show the channel inputs.

Note: Make sure you only render the channel inputs that match the format of the color picker.

const ColorPicker = () => {
  const [state, send] = useMachine(
    colorPicker.machine({
      id: useId(),
      value: colorPicker.parse("hsl(0, 100%, 50%)"),
    }),
  )

  const api = colorPicker.connect(state, send, normalizeProps)

  return (
    <div {...api.getRootProps()}>
      {/* ... */}
      <div {...api.getPositionerProps()}>
        <div {...api.getContentProps()}>
          {api.format === "rgba" && (
            <div>
              <div>
                <span>R</span>
                <input {...api.getChannelInputProps({ channel: "red" })} />

Showing a color preview

To display the value of a color, use the getSwatchProps(...) and pass the color value. To show the current color value, use the api.value

const ColorPicker = () => {
  const [state, send] = useMachine(
    colorPicker.machine({
      id: useId(),
      value: colorPicker.parse("hsl(0, 100%, 50%)"),
    }),
  )

  const api = colorPicker.connect(state, send, normalizeProps)

  return (
    <div {...api.getRootProps()}>
      <div>
        <div {...api.getTransparencyGridProps({ size: "4px" })} />
        <div {...api.getSwatchProps({ value: api.value })} />
      </div>
      {/* ... */}
    </div>
  )
}

const ColorPicker = () => {
  const [state, send] = useMachine(
    colorPicker.machine({
      id: createUniqueId(),
      value: colorPicker.parse("hsl(0, 100%, 50%)"),
    }),
  )

  const api = createMemo(() => colorPicker.connect(state, send, normalizeProps))

  return (
    <div {...api().getRootProps()}>
      <div>
        <div {...api().getTransparencyGridProps({ size: "4px" })} />
        <div {...api().getSwatchProps({ value: api().value })} />
      </div>
      {/* ... */}
    </div>
  )
}

<script setup>
import * as colorPicker from "@zag-js/color-picker";
import { normalizeProps, useMachine } from "@zag-js/vue";
import { computed } from "vue";

const [state, send] = useMachine(colorPicker.machine({
  id: "1",
  value: colorPicker.parse("hsl(0, 100%, 50%)")
}))

const api = computed(() => colorPicker.connect(state.value, send, normalizeProps));
</script>

<template>
  <div v-bind="api.getRootProps()">
    <div>
      <div v-bind="api.getTransparencyGridProps({ size: '4px' })" />
      <div v-bind="api.getSwatchProps({ value: api.value })" />
    </div>
    // ...
  </div>
</template>

<script lang="ts">
  import * as colorPicker from "@zag-js/color-picker"
  import { normalizeProps, useMachine } from "@zag-js/svelte"

  const [snapshot, send] = useMachine(colorPicker.machine({ id: "1", value: colorPicker.parse("hsl(0, 100%, 50%)") }))

  const api = $derived(colorPicker.connect(snapshot, send, normalizeProps))
</script>

<div {...api.getRootProps()}>
  <div>
    <div {...api.getTransparencyGridProps({ size: "4px" })}></div>
    <div {...api.getSwatchProps({ value: api.value })}></div>
  </div>
  <!-- ... -->
</div>

You can pass respectAlpha: false to show the color value without the alpha channel

Adding an eyedropper

The eye dropper tool is a native browser feature that allows a user pick a color from a current page's canvas. To support this, use the getEyeDropperTriggerProps(...).

Note: The eye dropper tool only works in Chrome and Edge browsers

const ColorPicker = () => {
  const [state, send] = useMachine(
    colorPicker.machine({
      id: useId(),
      value: colorPicker.parse("hsl(0, 100%, 50%)"),
    }),
  )

  const api = colorPicker.connect(state, send, normalizeProps)

  return (
    <div {...api.getRootProps()}>
      {/* ... */}
      <div {...api.getPositionerProps()}>
        <div {...api.getContentProps()}>
          <button {...api.getEyeDropperTriggerProps()}>
            <EyeDropIcon />
          </button>
        </div>
      </div>
    </div>
  )
}

const ColorPicker = () => {
  const [state, send] = useMachine(
    colorPicker.machine({
      id: createUniqueId(),
      value: colorPicker.parse("hsl(0, 100%, 50%)"),
    }),
  )

  const api = createMemo(() => colorPicker.connect(state, send, normalizeProps))

  return (
    <div {...api().getRootProps()}>
      {/* ... */}
      <div {...api().getPositionerProps()}>
        <div {...api().getContentProps()}>
          <button {...api().getEyeDropperTriggerProps()}>
            <EyeDropIcon />
          </button>
        </div>
      </div>
    </div>
  )
}

<script setup>
import * as colorPicker from "@zag-js/color-picker";
import { normalizeProps, useMachine } from "@zag-js/vue";
import { computed } from "vue";

const [state, send] = useMachine(colorPicker.machine({
  id: "1",
  value: colorPicker.parse("hsl(0, 100%, 50%)")
}))

const api = computed(() => colorPicker.connect(state.value, send, normalizeProps));
</script>

<template>
  <div v-bind="api.getRootProps()">
    // ...
    <div v-bind="api.getPositionerProps()">
      <div v-bind="api.getContentProps()">
        <button v-bind="api.getEyeDropperTriggerProps()">
          <EyeDropIcon />
        </button>
      </div>
    </div>
  </div>
</template>

<script lang="ts">
  import * as colorPicker from "@zag-js/color-picker"
  import { normalizeProps, useMachine } from "@zag-js/svelte"

  const [snapshot, send] = useMachine(colorPicker.machine({ id: "1", value: colorPicker.parse("hsl(0, 100%, 50%)") }))

  const api = $derived(colorPicker.connect(snapshot, send, normalizeProps))
</script>

<div {...api.getRootProps()}>
  <!-- ... -->
  <div {...api.getPositionerProps()}>
    <div {...api.getContentProps()}>
      <button {...api.getEyeDropperTriggerProps()}>
        <EyeDropIcon />
      </button>
    </div>
  </div>
</div>

Usage within forms

To use the color picker within a form, add the name context property to the machine and render the visually hidden input using the hiddenInputProps.

const [state, send] = useMachine(
  colorPicker.machine({
    name: "color-preference",
  }),
)

Styling guide

Each color picker part has a data-part attribute added to them to help you identify and style them easily.

Open and closed state

When the color picker is open or closed, the data-state attribute is added to the trigger, content, control parts.

[data-part="control"][data-state="open|closed"] {
  /* styles for control open or state */
}

[data-part="trigger"][data-state="open|closed"] {
  /* styles for control open or state */
}

[data-part="content"][data-state="open|closed"] {
  /* styles for control open or state */
}

Focused State

When the color picker is focused, the data-focus attribute is added to the control and label parts.

[data-part="control"][data-focus] {
  /* styles for control focus state */
}

[data-part="label"][data-focus] {
  /* styles for label focus state */
}

Disabled State

When the color picker is disabled, the data-disabled attribute is added to the label, control, trigger and option parts.

[data-part="label"][data-disabled] {
  /* styles for label disabled state */
}

[data-part="control"][data-disabled] {
  /* styles for control disabled state */
}

[data-part="trigger"][data-disabled] {
  /* styles for trigger disabled state */
}

[data-part="swatch-trigger"][data-disabled] {
  /* styles for item disabled state */
}

Swatch State

When a swatch's color value matches the color picker's value, the data-state=checked attribute is added to the swatch part.

[data-part="swatch-trigger"][data-state="checked|unchecked"] {
  /* styles for swatch's checked state */
}
