  <p>I tried to put <code>config(bg='#CCC9C1')</code> everywhere I can think of, but I managed to make only for some parts from dialog.  </p>
  
  <p>Is it possible to change bg color in tkSimpleDialog?</p>

  <p>Code sample:</p>
  
  <pre><code>from Tkinter import *
  import tkSimpleDialog
  
  class MyDialog(tkSimpleDialog.Dialog):
  
      def body(self, master):
  
          Label(master, text="First:").grid(row=0)
          Label(master, text="Second:").grid(row=1)
  
          self.e1 = Entry(master)
          self.e2 = Entry(master)
  
          self.e1.grid(row=0, column=1)
          self.e2.grid(row=1, column=1)
          return self.e1 # initial focus
  
      def apply(self):
          first = int(self.e1.get())
          second = int(self.e2.get())
          print first, second # or something
  
  root = Tk()
  root.withdraw()
  
  d = MyDialog(root)
  </code></pre>
