I believe that lithium + potassium contamination of the glass substrate leads to a magenta colour.  Wilson Link to post Share on other sites More sharing options...

wlaidlaw Posted June 1, 2015 Share #84  Posted June 1, 2015 Howlers. I like that term, Wilson.  It seems some with the retina display often have comment about color shifts. True? I think you have to be very disciplined about regular profiling with a Retina MBP display. I set mine to remind me every four weeks and use a Spyder 4 Pro. However the Retina doesn't drift very far compared with the NEC 24" monitor my wife uses on our old PowerMac Dual 2.3. She doesn't use it for photos that much (it is basically her server for patient medical records and billing, downloading from the medical app she uses on her iPad). When she does use it for her photos, she always comes through and says "the colours are horrible". I have to go and profile it.  I was waiting in at my local Apple dealer in Hove, UK, while the video card was replaced on my Retina, as I kept getting video crashes nearly every time the video switched from Intel to nVidia. I was playing with the new 5K iMac, which was very impressive. The salesman who was chatting to me and asked if I profiled my screen. When I said yes, he replied that I would need to do it a lot if I had a 5K iMac, as until it settled down, if you were using it for photography and needed accurate colour, he reckoned you needed to profile it at least once a week for the first two to three months.  Wilson Link to post Share on other sites More sharing options...
