Changing Background Color of ttk Buttons in Python

If you've ever attempted to customize the appearance of ttk buttons in Python's Tkinter library, you may have run into a frustrating issue: the button background color doesn’t change as expected. Instead, you might find that only the border color modifies while the button remains a default grey. This guide will help you understand how to solve this problem and achieve the desired look for your buttons.

Understanding the Problem

When you use the style method to modify ttk buttons, the expected changes sometimes do not take effect. Specifically, you might notice:

Border Color Changes: The border color may change according to your specifications.

Button Remains Grey: The button maintains its grey background regardless of the settings you change.

This can be particularly frustrating when you want your application's user interface to feel cohesive and appealing. Let’s dive into a solution that can help you overcome these limitations.

Solution: Use TLabel Instead

One effective workaround is to use the TLabel style instead of the traditional TButton. Here’s how you can implement this change:

Step-by-Step Implementation

Import Necessary Modules:
Begin by importing the required components from the tkinter and ttk modules.
