Purchased 2 5D III's and 1D X recently. The color on 5D III's leans to the green side. I have all settings in Adobe Camera Raw set the same for all cameras. Images are shot in RAW and on custom white balance in studio light on a target. I am using a color balanced monitor as well. I have 1D IV, 1D III, 1Ds III and 7D that do not have this shift to the green. I set the 5D III's to a +2 Magenta to compensate for the green and it does help in a properly exposed image. If an image is under exposed and pushed in ACR it will go even more green. I have samples taken in studio lighting with the same 24 70 2.8 L II lens and ISO 200 at f9 and f20 to produce underexposure. The link is here and the images are labeled.
Any help would be appreciated.
