# Color Picker Examples and Reference

### Default Color Picker

An example of a default Color Picker without any extra properties.

    using Dash
    using DashDaq

    external_stylesheets = ["https://codepen.io/chriddyp/pen/bWLwgP.css"]

    app = dash(external_stylesheets=external_stylesheets)

    app.layout = html_div([
      daq_colorpicker(
          id="my-color-picker",
          label="Color Picker",
          value=(hex ="#119DFF",)
      ),
      html_div(id="color-picker-output")
    ])

    callback!(app,
      Output("color-picker-output", "children"),
      [Input("my-color-picker", "value")]) do value
      return "The selected color is $value"
    end
    run_server(app, "0.0.0.0", debug=true)

Color Picker
hex
The selected color is {'hex': '#119DFF'}.

### Size

Set the size (width) of the color picker in pixels using the `size` property.

    using Dash
    using DashDaq

    app = dash()

    app.layout = daq_colorpicker(
      label="Small",
      size=164,
    )

    run_server(app, "0.0.0.0", debug=true)

Small
hex

### Label

Define the label and label position using the `label` and `labelPosition` properties.

    using Dash
    using DashDaq

    app = dash()

    app.layout = daq_colorpicker(
      label="Label",
      labelPosition="bottom"
    )

    run_server(app, "0.0.0.0", debug=true)

hex
Label

### Disabled

To disable the Color Picker set `disabled` to `true`.

    using Dash
    using DashDaq

    app = dash()

    app.layout = daq_colorpicker(
      label="Color Picker",
      disabled=true,
    )
    run_server(app, "0.0.0.0", debug=true)

Color Picker
hex

### Hex Colors

Use hex values with the Color Picker by setting `value=Dict(hex='#<hex_color>')`

    using Dash
    using DashDaq

    app = dash()

    app.layout = daq_colorpicker(
      label="Color Picker",
      value=(hex="#0000FF",),
    )
    run_server(app, "0.0.0.0", debug=true)

Color Picker
hex

### RGB Colors

Use RGB color values with the Color Picker by setting: `value=Dict("rgb"=(r=<r_value>, g=<g_value>, b=<b_value>, a=<a_value>))`

    using Dash
    using DashDaq

    app = dash()

    app.layout = daq_colorpicker(
      label="Color Picker",
      value=Dict("rgb"=>(r=255, g=0, b=0, a=0))
      )
    run_server(app, "0.0.0.0", debug=true)

Color Picker
r
g
b

## ColorPicker Properties

> Our recommended IDE for writing Dash apps is Dash Enterprise's Data Science Workspaces, which has typeahead support for Dash Component Properties. Find out if your company is using Dash Enterprise.

`id` (String; optional): The ID used to identify the color picker in Dash callbacks.

`value` (Dict; optional): Color value of the picker.

`value` is a Dict with keys:

- `hex` (String; optional): Hex string.

- `rbg` (Dict; optional): RGB/RGBA object.

  `rbg` is a Dict with keys:

  - `a` (Real; optional)

  - `b` (Real; optional)

  - `g` (Real; optional)

  - `r` (Real; optional)

`disabled` (Bool; optional): If true, color cannot be picked.

`size` (Real; default `225`): Size (width) of the component in pixels.

`theme` (Dict; default `light`): Theme configuration to be set by a ThemeProvider.

`label` (Dict; optional): Description to be displayed alongside the control. To control styling, pass an object with label and style properties.

`label` is a String | Dict with keys:

- `label` (String; optional)

- `style` (Dict; optional)

`labelPosition` (a value equal to: 'top' or 'bottom'; default `'top'`): Where the indicator label is positioned.

`className` (String; optional): Class to apply to the root component element.

`style` (Dict; optional): Style to apply to the root component element.

`persistence` (Bool | String | Real; optional): Used to allow user interactions in this component to be persisted when the component - or the page - is refreshed. If `persisted` is truthy and hasn't changed from its previous value, a `value` that the user has changed while using the app will keep that change, as long as the new `value` also matches what was given originally. Used in conjunction with `persistence_type`.

`persisted_props` (Array of values equal to: 'value'; default `['value']`): Properties whose user interactions will persist after refreshing the component or the page. Since only `value` is allowed this prop can normally be ignored.

`persistence_type` (a value equal to: 'local', 'session' or 'memory'; default `'local'`): Where persisted user changes will be stored: memory: only kept in memory, reset on page refresh. local: window.localStorage, data is kept after the browser quit. session: window.sessionStorage, data is cleared once the browser quit.
