how to match the color back ground of my frame with the master window

Question

thats the program in python using tkinter and customtkinter:

import customtkinter


def login():
    if email_entry.get() == "admin" and password_entry.get() == "password":
        message_label.configure(text="Login successful!")
    else:
        message_label.configure(text="Invalid username or password")

def sign_user():
    print('open another page and make the log')

def help_user():
    print('forget password?')

# window
window = customtkinter.CTk()
window.title("Agenda de Rotina")
window.geometry('500x300+710+390')
window.resizable(False, False)
customtkinter.set_appearance_mode('dark')

#create the frame to email and password
frame_1 = customtkinter.CTkFrame(window)
frame_1.pack(pady=(70, 5))

# create the email and password entry widgets
email_label = customtkinter.CTkLabel(frame_1, text="E-mail:")
email_label.grid(row=0, column=0, padx=5, pady=5)
email_entry = customtkinter.CTkEntry(frame_1)
email_entry.grid(row=0, column=1, padx=5, pady=5)

password_label = customtkinter.CTkLabel(frame_1, text="Password:")
password_label.grid(row=1, column=0, padx=5, pady=5)
password_entry = customtkinter.CTkEntry(frame_1)
password_entry.grid(row=1, column=1, padx=5, pady=5)

# create the login button
login_button = customtkinter.CTkButton(window, text="Login", command=login)
login_button.pack(pady = 10)

# create a label for displaying messages
message_label = customtkinter.CTkLabel(window, text="")
message_label.pack()

# create the frame to the sign and help? button
frame_2 = customtkinter.CTkFrame(window)
frame_2.pack(pady = 10)

# create the sign and need help? button
sign_button = customtkinter.CTkButton(frame_2, text = 'Sign', width = 100, command = sign_user)
sign_button.grid(row = 0, column = 0, padx = (0, 10))
help_button = customtkinter.CTkButton(frame_2, text = 'Help?', width = 100, command = help_user)
help_button.grid(row = 0, column = 1, padx = (10, 0))


window.mainloop()

and i used this appearance_mode:

customtkinter.set_appearance_mode('dark')

but i want to to my frame background color be the same as my bg window. I have tried to set, but doesn't work.

my_window_dark = '#242424'

# and i put the variable in the frame
frame_1 = customtkinter.CTkFrame(window, bg_color = 'my_window_dark')
frame_1.pack(pady=(70, 5))

and when i just put a random color to see what hapens:

i tried to creat a variable to the color and them put that variable in the color method of the frame, and get an error. Also when i put a random color that is in the lib, appear the image that i put above

You can simply use the special color "transparent":

frame_1 = customtkinter.CTkFrame(window, fg_color="transparent")
