Yeah but it shouldn't be, it should be grey because when I bring up the quick settings when I'm not in my home screen, it looks red still and ugly. I actually changed wallpaper now to a blue colour and the quick settings background have that blue ish tint now, although I don't have the colour palette enabled or any themes. Applying a colour palette to grey makes them grey but that's a bug I would say, should just be grey by default.
