在Python 2.7中更改Tkinter窗口的背景颜色

Question

我正在使用函数tkFileDialog.askopenfilename()要求用户选择文件路径。问题是，由于我使用的黑暗主题，文字是浅灰色。窗口的背景应该是黑色的（在系统的其余部分它是黑色的），但由于某些原因在tkinter窗口中它仍然是白色的。这是一个截图：

如您所见，文字几乎无法读取。

我尝试使用.configure(background='black')更改窗口背景的颜色，但没有成功......有人可以帮忙吗？

非常感谢！

编辑：或者，我也很乐意将文字颜色改为黑色......白色不是浅灰色！

从tkinter的源代码中我看不到任何允许为askopenfilename()更改背景的选项。

来自代码：

# For the following classes and modules:
#
# options (all have default values):
#
# - defaultextension: added to filename if not explicitly given
#
# - filetypes: sequence of (label, pattern) tuples.  the same pattern
#   may occur with several patterns.  use "*" as pattern to indicate
#   all files.
#
# - initialdir: initial directory.  preserved by dialog instance.
#
# - initialfile: initial file (ignored by the open dialog).  preserved
#   by dialog instance.
#
# - parent: which window to place the dialog on top of
#
# - title: dialog title
#
# - multiple: if true user may select more than one file
#
# options for the directory chooser:
#
# - initialdir, parent, title: see above
#
# - mustexist: if true, user must pick an existing directory
#
