Macos appearance colors not found in tkinter.

[Saadmairaj]

Describe the bug
The appearance colors like "systemWindowBackgroundColor" and "systemTextColor" are giving error _tkinter.TclError: unknown color name for some macOS for some people but on my machine they work perfectly fine.

To Reproduce

import tkinter as tk
from tkmacosx import Button

window = tk.Tk()
button = Button(window, text='Text')#, highlightbackground='gray15', fg='pink')
button.pack()
window.mainloop()

Expected behavior

fwiw, I also encountered the this issue without tkmacosx, but when trying to use the MacOS system colors on a regular tk.Button.

BigSur 11.3.1 + Python 3.9.5

If I install Python via the macOS 64-bit Intel installer, then I have this issue.
If I install Python via the macOS 64-bit universal2 installer, then everything works oke.
