Tkinter button background color is not working in mac os

Question

I am trying to change the bg color of a tkinter button on my mac (catalina) but instead of getting a colored background, it is showing a blank white space in the layout.

The button code I used:

button_open = Button(root, width=45, bg="#82CC6C", fg="black", text="OPEN",
                     highlightbackground="#82CC6C", highlightthickness=1,
                     borderwidth=0.2, relief="groove", padx=0, pady=0)
    
button_open.grid()

Result I am getting:

What I expected:

I tried changing all the parameters but it is always giving me the same result,

How can we fix this? Is it a bug in tkinter on mac only?
