One more. Change background color with button click in tkinter.

import tkinter as tk
from random import randint
def rgb(label):
    color = tuple(randint(0, 255) for i in range(3))
    label['bg'] = f'#%02x%02x%02x' % color
root = tk.Tk()
label = tk.Label(root, width=50, height=20, relief='groove')
label.pack(padx=5, pady=4)
button = tk.Button(root, text='change color', command=lambda:rgb(label)).pack(expand=True, fill='both', padx=5, pady=4)
root.mainloop()
