Customize the background color and text color of a customTkinter window title bar

For my application, I'd like the native customkinter bar to change color and the text color too. I found a lot of weird libraries that did this, but it didn't work. For your information, because it's important to my problem, my operating system is Window10.

To help you with my problem, I'll give you the code for the initialization method of my class:

import customkinter

class FenetreLogin(customtkinter.CTk):
    def __init__(self):
        super().__init__();
        
        self.geometry("700x680");
        self.title("Exportation_Fanny v1");
        self.initial_width = 650;
        labelAuteur = customtkinter.CTkLabel(master=self,font=("",20,'underline'),text="Made By Lucas Desperrois");
        labelAuteur.pack(anchor="n",pady=10)
        self.resizable(width=False,height=False)
        self.fenetreConnexion = self.frameConnexion();
        self.browser1=None;

This is what I use:

import customtkinter as ctk
import os
from ctypes import byref, c_int, sizeof, windll 

class App(ctk.CTk):
    def __init__ (self):
        super().__init__()

        self.title("")

        try:
            self.iconbitmap(os.path.join(os.path.dirname(__file__), "images/empty.ico"))    # an empty icon
        except:
            pass

        # change the title bar color to a discord like color #5662f6
        self.title_bar_color("#5662f6")

    def title_bar_color(self, hexcolor):
      color = '0x00'
      for i in range(7,0,-2):
         h = hexcolor[i:i+2]
         color = color+h
      windll.dwmapi.DwmSetWindowAttribute(
            windll.user32.GetParent(self.winfo_id()), 
            35, 
            byref(c_int(int(color, 16))), 
            sizeof(c_int)
            )

        
if __name__ == "__main__":
      app = App()
      app.mainloop()

Now for this code to work, you need to do 2 things:

1. Download an empty .png and convert it to .ico format so that you can remove the logo on the app (don't forget to change the directory to wherever you put your image)
2. Get the hex code for whatever color you want
