title: Python background color of main frame
body: <p>I want my main frame to have the background color black. Here is what I tried:</p>
  
  <pre><code>#!/usr/bin/python
  import tkinter
  from tkinter import *
  
  root = Tk()
  root.geometry("363x200")
  root.resizable(0,0)
  root.title("Emsg Server")
  root.option_add("*background", "black")
  
  v = StringVar()
  
  Field = Message(root, textvariable=v, width=330, fg="blue")
  Field.grid()
  
  root.mainloop()
  </code></pre>
  
  <p>My attempt above with <code>root.option_add("*background", "black")</code>, just creates one single small black box located north west.</p>
  
  <p>How do you make the entire application black?</p>
