"tkinter.colorchooser" --- Color choosing dialog
************************************************

**Source code:** Lib/tkinter/colorchooser.py

======================================================================

The "tkinter.colorchooser" module provides the "Chooser" class as an
interface to the native color picker dialog. "Chooser" implements a
modal color choosing dialog window. The "Chooser" class inherits from
the "Dialog" class.

class tkinter.colorchooser.Chooser(master=None, **options)

tkinter.colorchooser.askcolor(color=None, **options)

   Create a color choosing dialog. A call to this method will show the
   window, wait for the user to make a selection, and return the
   selected color (or "None") to the caller.
