These images were taken one after the other using the same lens, left D7000 right D7100. The raw images were extracted by ACR and assembled in PS without corrections. Conditions were under heavily overcast sky with Auto WB. The auto WB went a bit more blue-ish on the D7100, clearly visible in the skin colour. This may easily be adjusted in PP.

The most striking is the colour of the windbreaker: clearly blue according to both images. It appears that way in images consistently. To the eye the windbreaker is consistently and clearly "green"! Below is a version with the windbreaker corrected to the proper eyeball colour.

The hue shift needed is about -30 for the D7000 windbreaker colour to arrive at the eye observed blue green - left image below. For the D7100 the required hue shift is reduced to about -20 - not shown here. To conclude, I like the slight progress in colour differentiation coming with the D7100.

You might be seeing the difference in how Adobe Standard in ACR (which is actually different for the two cameras) is processing the image.

Here are two RAW nef's of the same cameras processed with Nikon software (no PP other than conversion).

If you make your NEF's available...might be cool to see what happens with the jacket with Nikon conversion and WB held constant. Very interesting. Thanks
