[Tkinter-discuss] Changing title bar color in Tkinter

[Jeff Epler]

No.  It is not Tkinter that draws the title bar of the window, but the
window manager.  

You can cause the window manager not to draw any decorations on the
window by setting the wm_override() but this also means you lose the
ability to move and resize the window in the normal way.  Usually this
is a bad choice for application windows.
