D800 Orange Burn: Little Help, Please?

You need to provide a lot more details in order for  the forum to offer relevant advice.

You say it's not WB, but I have never seen skin tones look like that unless it was WB when using a proper post processing workflow.  What you need to provide is all the details with regard to camera set up (raw, jpeg, picture control, etc) as well as the workflow in post (photo editor, picture control or camera preset, color space, etc).

I would have suggested the use of something like a Color Checker generated camera profile if you were using Adobe software.  However, this orange skin tone is so far out of whack that I doubt that is a solution.  Something else is causing the problem here.
