title: How to change the background color of the box in tkinter (python)
body: <p>I am new to the python language, and I have been learning tkinter. However I wonder how can I change the background of the box that pops up in tkinter.</p>
  
  <pre><code>import time
  import tkinter
  from tkinter import *
  import sys
  import os
  root = tkinter.Tk()
  </code></pre>
  
  <p>Using this you get a grey box that pops up. How to I change the color of that box?</p>
