[issue45270] Clicking "Add to Custom Colors" adds same colour multiple times

I understand that, but is it possible to keep only unique colors in the
Custom Color palette, and when user chooses the exact same color to be in
the Custom Color palette it would return a pop up like "Color already in
Custom Color palette".

It would be better if the color strings which IDLE receives, are checked if
present already in Custom Colors, if not it then passes it to tkinter and
tk.
