best way to locate a color changing button

Question

The code I currently have is:

import pyautogui

location_button = pyautogui.locateOnScreen('Button.png')
x, y = pyautogui.center(location_button)
pyautogui.click(x, y)

The code tries to find a exact image of Button.png on the screen, get the coordinate, and click the coordinate.

The problem is that the Button changes color gradually, so sometimes location_button returns None. What is the best way to get a positive match all the time even if the button color changes?

Greyscale doesn't because there are particles flying around sometimes get in the Button.

Would binary image work?

Thanks

Create image files for all the different button colors, named Button0.png, Button1.png, etc., and search for them in a loop.

for i in range(button_image_count):
    location_button = pyautogui.locateOnScreen('Button%d.png' % 10)
    if location_button:
        break
