每次运行 Tkinter 程序时，我都会在 shell 中收到此消息：
WARNING: Appearance colours are not either supported with the current tkinter or the colors doesn't exist on this Mac.
但是，颜色有效，我的按钮看起来不错：
roll=Button(window, text="Roll the Dice", background="red", fg="white", activebackground='#00FF00',font=("Calibri",(30)), width =180, height = 55, borderless=1)
虽然这不是错误...
谢谢
