When I edit an image and save it in PSD format it gets (most of the time) a pink hue. At first I thought it was because they were 16 bit depth, so I converted to 8bit. Seemed to help. Now I edited some first in Lightroom 4 and then finisehd in Photoshop and again I get the shift. Colors stay true when saving in TIFF format though. Working in Windows7 64 bit.
