Background Button Color is not working properly MACOS

问题

我正在尝试为学校项目制作一个简单的GUI。我对使用tkinter还很陌生。我过去通常使用pygame来创建我的GUI，它非常适合自定义，但效率不太高哈哈。

我为我的/graphs文件夹中的每个文件创建了一个按钮。在这段代码中，第42行，我似乎无法更改按钮的背景颜色。这是我在使用tkinter时经常遇到的问题。我不知道是我做错了什么，还是我使用的框架存在问题。

我尝试使背景颜色变为红色。

我正在使用MACOS，我知道tkinter和mac之间存在一些复杂性，但我不能使用tkmacosx，因为我需要这个项目能够在Windows和Linux上运行。

谢谢你的帮助，如果你有关于tkinter常见实践的建议，我没有应用，或者你有解决我的问题的方法，请不要犹豫！

以下是输出和代码：

import tkinter as tk
import os

# 颜色
SILVER = "#BFACAA"
BLACK = "#02020A"
OXFORD_BLUE = "#05204A"
WISTERIA = "#B497D6"
LAVENDER = "#E1E2EF"
RED = "#FF0000"

# 尺寸
WIDTH = 800
HEIGHT = 600

# 路径
PRJ_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))


class Window:
    def __init__(self):
        self.window = tk.Tk()
        self.window.title("Graph Scheduler")
        self.window.geometry(f"{WIDTH}x{HEIGHT}")
        self.window.configure(background=LAVENDER)

        # 标题和标题框
        title_box = tk.Frame(self.window, bg=SILVER, width=WIDTH)
        title_box.pack(fill="x")
        title = tk.Label(title_box, text="Graph Scheduler", font=("Arial", 40), bg=SILVER, fg=BLACK)
        title.pack(pady=5)

        # 文件栏
        file_bar = tk.Frame(self.window, bg=OXFORD_BLUE, width=200, height=HEIGHT)
        file_bar.pack(fill="y", side="left")

        # 文件栏按钮
        file_bar_buttons = tk.Frame(file_bar, bg=OXFORD_BLUE, width=200, height=HEIGHT)
        file_bar_buttons.pack(fill="y", side="left")
        for file in os.listdir(PRJ_DIR + "/graphs"):
            if file.endswith(".txt"):
                file_bar_button = tk.Button(file_bar_buttons, text=file, background=RED, fg=SILVER, font=("Arial", 20), width=10, height=2)

I am trying to make a simple GUI for a school project. I am new to using tkinter. I used to create my GUIs using pygame, which is great for custumization, but not really for efficiency haha.

I am creating a button for each file in my /graphs folder. In this code, line 42, it seems to me I can&#39;t change the background color of the button. This is a reccurent problemI have with tkinter. I have no idea if it is something I am doing wrong or if there is a problem with the framework I am using. 

I am trying to make the bg color red.

I am using MACOS, and i know there are complications with tkinter and mac, but i can&#39;t use tkmacosx because i need this project to be runnable on windows and linux as well.

Thank you for your help, don&#39;t hesitate if you have any suggestions on common practices with tkinter that i am not applying or if you have the solution to my problem !

Here is the output and the code
