 pygame.display.set_palette()
    Set the display color palette for indexed displays
    set_palette(palette=None) -> None

This will change the video display color palette for 8-bit displays. This does not change the palette for the actual display Surface, only the palette that is used to display the Surface. If no palette argument is passed, the system default palette will be restored. The palette is a sequence of RGB triplets.

It's easy to emulate this with OpenGL, or to have a layer of indirection to perform the palette swap every time on pygame.display.update. I'm not sure if it's worth implementing the ugly but reliable solution here.

(The ugly but reliable solution would be to do the palette-swap in software. OpenGL is out of the question for reasons of portability. Even doing the swap with Renderer would mean adding fuctionality to upsteam SDL2)

From what I can tell, there is no easy solution for this. There are some users of this function, so it's important. However, there's no way to address it before the release of pygame 2 on the 28th of Oct. For these reasons I'll remove the critical label, and this can be added to a list of things that are not compatible (along with cdrom, and scrap) in the release.
