How can I change the background color if this argument doesn't work, and why isn't it working?

I am a beginner in Python. I coded a script with
tkinter, but I have a button that doesn't work:
generate_button = Button(right_frame, text="Generate", font=("Arial", 20), bg='#68F004', fg='white', relief=SUNKEN, bd=0, highlightthickness=0, command=generate_passwd) Even though I set
bg='#68F004', I get a gray background instead of green.
How can I change the background color if this argument doesn't work, and why isn't it working?
Thank you in advance,

Thank you all for helping me!
In the end, it was yg_be who found the answer, which can be consulted here:

On MacOS, buttons are handled differently. Tkinter fails to change the button's background color for this reason. Fortunately, there is a module, tkmacosx, to import in addition to Tkinter. It retains the Tkinter commands, but corrected for MacOS. This allows me to change the bg and gives the button a more "mac" look.
The result with Tkmacosx combined with Tkinter is as follows:
Thank you to everyone who took some time to try to help me; it warms the heart to see that there is still some mutual support in this crazy world.

Hello,
Strange, it works for me:
Maybe with the complete code, we could see more clearly...-
Hello,
The complete code is:
import string from random import randint, choice from tkinter import * def generate_passwd(): passwd_min = 6 passwd_max = 18 all_chars = string.ascii_letters + string.punctuation + string.digits password = "".join(choice(all_chars)for x in range(randint(passwd_min, passwd_max))) password_entry.delete(0, END) password_entry.insert(0, password) window = Tk() window.title("Password Generator") window.geometry() window.minsize(720, 480) window.iconbitmap('logo.png') window.config(background='#5EFBDC') frame = Frame(window, bg='#5EFBDC') # add image width = 300 height = 300 image = PhotoImage(file="logo.png").zoom(50).subsample(60) canvas = Canvas(frame, width=width, height=height, bg='#5EFBDC', bd=0, highlightthickness=0) canvas.create_image(width/2, height/2, image=image) canvas.grid(row=0, column=0, sticky=W) right_frame = Frame(frame, bg='#5EFBDC') label_title = Label(right_frame, text="Password", font=("Helvetica", 20), bg='#5EFBDC', fg='white') label_title.pack() # create a field/input password_entry = Entry(right_frame, font=("Helvetica", 20), bg='#5EFBDC', fg='white') password_entry.pack() # create a button generate_button = Button( right_frame, text="Generate", font=("Arial", 20), bg='#68F004', fg='#68F004', relief=SUNKEN, bd=0, highlightthickness=0, command=generate_passwd ) # curiously the argument 'bg=' has no effect and the background remains gray while it should be green. generate_button.pack(pady=10, fill=X) right_frame.grid(row=0, column=1, sticky=W) frame.pack(expand=YES) # create menu bar menu_bar = Menu(window) file_menu = Menu(menu_bar, tearoff=0) file_menu.add_command(label="New", command=generate_passwd) file_menu.add_command(label="Quit", command=window.quit) menu_bar.add_cascade(label="File", menu=file_menu) window.config(menu=menu_bar) window.mainloop()
I know it is not properly organized into functions, but it doesn't seem to affect the execution of my program.
Thank you,

At my place, it works, the only thing is that since fg = bg, green on green, you can't see the text on the button
-
bg = fg because I was trying to set bg to #68F004, but since it remained gray, I also set fg to #68F004 because it was white and therefore unreadable in white on light gray.
I will try to update Tkinter and see if that resolves the issue.-

I see here several suggestions for solutions or workarounds.

It seems that on Linux, my program works perfectly. The button does indeed have that green color. It may be an incompatibility with button management in MacOS.
