"tkinter.colorchooser" --- 颜色选择对话框
*****************************************

**源代码:** Lib/tkinter/colorchooser.py

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

"tkinter.colorchooser" 模块提供了 "Chooser" 类作为原生颜色选取器对话框
的接口。"Chooser" 实现了一个模态颜色选择对话框窗口。"Chooser" 类继承自
"Dialog" 类。

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

   The class implementing the modal color-choosing dialog. Most
   applications use the "askcolor()" convenience function rather than
   instantiating this class directly.

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

   Show a modal color-choosing dialog and return the chosen color.
   *color* is the color selected when the dialog opens. The return
   value is a tuple "((r, g, b), hexstr)", where "r", "g" and "b" are
   the red, green and blue components as integers in the range 0–255
   and *hexstr* is the equivalent Tk color string, such as
   "'#ff8000'". If the user cancels the dialog, "(None, None)" is
   returned.

   在 3.10 版本发生变更: The RGB values in the returned color are now
   integers in the range 0–255 instead of floats.
