    Fields
    Modifier and Type | Field and Description
    --- | ---
    `protected ChangeEvent` | `changeEvent` Only one `ChangeEvent` is needed per model instance since the event's only (read-only) state is the source property.
    `protected EventListenerList` | `listenerList`

  - ### Constructor Summary

    Constructors
    Constructor and Description
    `DefaultColorSelectionModel()` Creates a `DefaultColorSelectionModel` with the current color set to `Color.white`.
    `DefaultColorSelectionModel(Color color)` Creates a `DefaultColorSelectionModel` with the current color set to `color`, which should be non-`null`.

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `addChangeListener(ChangeListener l)` Adds a `ChangeListener` to the model.
    `protected void` | `fireStateChanged()` Runs each `ChangeListener`'s `stateChanged` method.
    `ChangeListener[]` | `getChangeListeners()` Returns an array of all the `ChangeListener`s added to this `DefaultColorSelectionModel` with `addChangeListener`.
    `Color` | `getSelectedColor()` Returns the selected `Color` which should be non-`null`.

- - ### Field Detail

    - #### changeEvent

          protected transient ChangeEvent changeEvent

      Only one `ChangeEvent` is needed per model instance since the event's only (read-only) state is the source property. The source of events generated here is always "this".

    - #### listenerList

          protected EventListenerList listenerList

  - ### Constructor Detail

    - #### DefaultColorSelectionModel

          public DefaultColorSelectionModel()

      Creates a `DefaultColorSelectionModel` with the current color set to `Color.white`. This is the default constructor.

    - #### DefaultColorSelectionModel

          public DefaultColorSelectionModel(Color color)

      Creates a `DefaultColorSelectionModel` with the current color set to `color`, which should be non-`null`. Note that setting the color to `null` is undefined and may have unpredictable results.
      Parameters:
        `color` - the new `Color`

  - ### Method Detail

    - #### getSelectedColor

          public Color getSelectedColor()

      Returns the selected `Color` which should be non-`null`.
      Specified by:
        `getSelectedColor` in interface `ColorSelectionModel`
      Returns:
        the selected `Color`
      See Also:
        `ColorSelectionModel.setSelectedColor(java.awt.Color)`

    - #### setSelectedColor

          public void setSelectedColor(Color color)

      Sets the selected color to `color`. Note that setting the color to `null` is undefined and may have unpredictable results. This method fires a state changed event if it sets the current color to a new non-`null` color; if the new color is the same as the current color, no event is fired.
      Specified by:
        `setSelectedColor` in interface `ColorSelectionModel`
      Parameters:
        `color` - the new `Color`
      See Also:
        `ColorSelectionModel.getSelectedColor()`, `ColorSelectionModel.addChangeListener(javax.swing.event.ChangeListener)`

    - #### addChangeListener

          public void addChangeListener(ChangeListener l)

      Adds a `ChangeListener` to the model.
      Specified by:
        `addChangeListener` in interface `ColorSelectionModel`
      Parameters:
        `l` - the `ChangeListener` to be added

    - #### removeChangeListener

          public void removeChangeListener(ChangeListener l)

      Removes a `ChangeListener` from the model.
      Specified by:
        `removeChangeListener` in interface `ColorSelectionModel`
      Parameters:
        `l` - the `ChangeListener` to be removed

    - #### getChangeListeners

          public ChangeListener[] getChangeListeners()

      Returns an array of all the `ChangeListener`s added to this `DefaultColorSelectionModel` with `addChangeListener`.
      Returns:
        all of the `ChangeListener`s added, or an empty array if no listeners have been added
      Since:
        1.4

    - #### fireStateChanged

          protected void fireStateChanged()

      Runs each `ChangeListener`'s `stateChanged` method.
      See Also:
        `EventListenerList`
