Cant change Progressbar color from tkinter to red

Question

I've seen some solutions to change the color of the Progressbar, however, when trying to apply them, it doesn't work and stays green.

I am probably missing a stupid thing.

This is a progressbar that is vertical, and it takes 10 seconds to fill. All I want is that the bar becomes red instead of green.

from tkinter import *
from tkinter.ttk import *
import time
root = Tk()
root.geometry("500x500")
seconds = 10
s = Style()
s.configure("red.Vertical.TProgressbar", foreground = 'red', background = 'red', throughcolor = 'red')
progress = Progressbar(root, orient = VERTICAL, length = 9999999, mode = 'determinate')
progress.configure(style = 'red.Vertical.TProgressbar')
progress.pack(ipadx = 200000, padx = 50, pady = 50) 
start_time = time.time()
elapsed_time = time.time() - start_time

while elapsed_time/seconds*100 < 100:
    progress['value'] = elapsed_time/seconds*100
    elapsed_time = time.time() - start_time
    root.update()
    time.sleep(0)

I tried that exact code without anything else and it still had a green bar — Moacir, Oct 31 '19 at 13:44
I don't believe you. When I run it in Python 3.8, the bar is red. — Ethan Field, Oct 31 '19 at 14:24
I think the problem was that I wasnt using the theme and instead was trying to copy paste only the lines that I 'thought' would work — Moacir, Oct 31 '19 at 16:38

Try this one:

import time
import tkinter  as tk
from  tkinter import  ttk
root = tk.Tk()
root.geometry("500x500")
seconds = 10
s = ttk.Style()
s.theme_use('clam')
s.configure("red.Vertical.TProgressbar", foreground='red', background='red')
progress = ttk.Progressbar(root, style="red.Vertical.TProgressbar", orient="vertical", length=600, mode="determinate", maximum=4, value=1)
progress.pack(ipadx = 200000, padx = 50, pady = 50)

start_time = time.time()
elapsed_time = time.time() - start_time

while elapsed_time/seconds*100 < 100:
    progress['value'] = elapsed_time/seconds*100
    elapsed_time = time.time() - start_time
    root.update()
    time.sleep(0)

I have also green when have tried your variant.

It worked. The line missing was the `s.theme_use('clam')` – Moacir Oct 31 '19 at 14:34 — Moacir, Oct 31 '19 at 14:34
