Why is my keyboard purple
My ipad (4th gen) keyboard turns yellow quickly and then the qwerty keys stay purple when transitioning from landscape to portrait mode. Any idea why this happens? I can't find anywhere to turn it off. Purple glowing keys when in portrait. No idea why. It doesn't mention anything in the manual and searching the Internet does no good as all I find is ads for purple keyboards to buy.
