I've been observing temporary super-pink tints on both my iPad Mini Retina as well as my Retina Macbook Pro. This happens infrequently and I'm not bothered by it at all, as it always goes away by itself - but I'm incredibly curious what is behind it. So what usually happens, is my iPad or rMBP are asleep, I wake them and sometimes - not always - for the first 5-10 minutes the displays are severely pink. The first time, I experienced it on my iPad mini retina at the airport. I had been reading on it in the cab the entire time, it was totally fine, all the whites were clean white. Arriving at the airport, I put it into its sleeve while making my way through security and pulled it out again at the gate, hoping to continue my reading. The moment I turned the screen back on, I was like ... all the whites on the screen were bright pink. I initially thought my eyes were playing a trick on me, since there was very bright natural light at the airport (windows all around the gates), but just holding a piece of paper next to iPad's screen showed clearly that there was indeed some pink madness going on. I turned the screen brightness up and down, turned the iPad off and on and off again ... the pink stuck. I put it back into my sleeve, thinking I'd deal with that "broken display" after my flight - when I pulled it out 3 hours later everything was back to normal and the whites were exactly as white as the paper sheets I used for reference. Since then I had gotten this iPad mini replaced for an unrelated issue and also the new unit sometimes wows me for a couple minutes with extreme pink. Then it looks completely normal again. Then, in January I got my rMBP and when I first switched it on, it had the same stark pink hue on the display in a bright room full of natural light. Even the Apple logo on the back glowed pink/purplish. I did the same "white balance" with a sheet of paper and my white walls and curtains to make sure it weren't my eyes playing a trick on me, but the screen definitely was super-pink. After a couple hours it went away and its whites matched the white of my walls and papers. Today, I woke up my rMBP and the pink veil was back on. After 10 minutes it was gone and all is well. I'm not troubled by it at all (please don't think I came here to worry or complain, that's really not my intention), but I'm super curious to what is causing this? Do the lights behind the retina displays not all come on simultaneously and the non-pink colours take a while to reach their full power? Like a classical neon-light that's dim and flickering for a couple of minutes till it becomes steady and bright? Or is it a matter of the light sensor getting overwhelmed in extremely bright natural light like a camera sensor that's struggling with the Auto White Balance? If you know the mystery's solution, please share your wisdom with me!
