The button text and color does not appear on Tkinter program

Question

The program works fine on other computers that run window's or ubuntu but the text won't show on the buttons. Here's a snippet of a longer code:

from Tkinter import *

from math import atan
from math import log
import math
import matplotlib
matplotlib.use('TkAgg')
import matplotlib.pyplot as plt



# --- function ---


def create_first_frame():
    global root
    global frame

    # frame.destroy()

    frame = Frame(bg="blue")
    frame.pack()

    label1 = Label(frame, text="hello!", fg="white", bg="blue", font="normal 30")
    label1.pack()

    button1 = Button(frame, text="Enter", fg="white", bg="blue", font="normal 20")
    button1.pack()

    button2 = Button(frame, text="Exit", font="normal", fg="white", bg="red", command=root.destroy)

    button2.pack(side=LEFT)




root = Tk()
create_first_frame()
root.mainloop()

We were expecting words like "start" and "exit" to show.

We just want the colors of the buttons to show along with the text

Answer 1

I am not sure what the question is. I took out unnecessary imports, and ran

from tkinter import *

def create_first_frame():
    global root
    global frame

    # frame.destroy()

    frame = Frame(bg="blue")
    frame.pack()

    label1 = Label(frame, text="hello!", fg="white", bg="blue", font="normal 30")
    label1.pack()

    button1 = Button(frame, text="Enter", fg="white", bg="blue", font="normal 20")
    button1.pack()

    button2 = Button(frame, text="Exit", font="normal", fg="white", bg="red", command=root.destroy)

    button2.pack(side=LEFT)

root = Tk()
create_first_frame()
root.mainloop()

Which creates for me:

This is colored as you have specified...
