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.

IMO, the image is filled with green which is throwing off the camera's color balance. Shoot the same guy, jacket, etc.  but with a neutral color background and see what happens.
