you can import ttk and use different styles within tkinter and create your own custom theme but apart from that not unless you use a different module
(note ttk is a stock python module)
for example
import tkinter
from tkinter import ttk
mycolour = "color code here"
mybackground = "color code here"
style = ttk.Style()
style.theme_create( "custom_theme", parent="alt", settings={
"TNotebook": {"configure": {"tabmargins": [2, 5, 2, 0] } },
"TNotebook.Tab": {
"configure": {"padding": [5, 1], "background": mycolour },
"map": {"background": [("selected", mybackground)],
"expand": [("selected", [1, 1, 1, 0])] } } } )
style.theme_use("custom_theme")
