  - ### listenerList

    protected EventListenerList listenerList
    The listener list.

- ## Constructor Details

  - ### 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 Details

  - ### 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(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`

  - ### 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`

      `l` - the `ChangeListener` to be removed

  - ### getChangeListeners

    public ChangeListener[] getChangeListeners()
    Returns an array of all the `ChangeListener`s added to this `DefaultColorSelectionModel` with `addChangeListener`.
