How to set a user-selected background colour in tkinter?

How to take user-selected colour and use it as the background colour of the tkinter frame?

list2 = ["red", "red", "red", "red", "blue", "yellow"];
droplist = OptionMenu(root, c, *list2)
droplist.config(width=15)
c.set('select your colour')
droplist.place(x=240, y=320)
root.configure(bg=c)

Let's make this work by filling in some missing pieces:

import tkinter as tk

COLORS = ["red", "blue", 'green', 'cyan', 'magenta', "yellow"]

def change_color(*args):
    root.configure(bg=color.get())

root = tk.Tk()
root.minsize(width=200, height=200)

color = tk.StringVar(root)
color.trace('w', change_color)
color.set(COLORS[0])

om = tk.OptionMenu(root, color, *COLORS)
label = tk.Label(root, text='Select your color')

om.pack(side="top")
label.pack(side="top")

root.mainloop()

The primary missing piece was the StringVar associated with the OptionMenu which allows you to interogate it. To associate a callback function with the OptionMenu, we trace changes to the StringVar.
