I'm recieving this message in the shell each time I run my Tkinter program:
WARNING: Appearance colours are not either supported with the current tkinter or the colors doesn't exist on this Mac.
However, the colours work and my button looks fine:
roll=Button(window, text="Roll the Dice", background="red", fg="white", activebackground='#00FF00',font=("Calibri",(30)), width =180, height = 55, borderless=1)
It isn't an error though...
Thanks
