6D Mark II Color Cast

Anyone else noticed strange color casts with JPEGs ? It’s like green shift ? Not sure If this is the lens, camera, or user error but seeing either green or magenta shifts quite a bit. I played with white balance settings with no luck. Images were shot under natural window lighting. Take a look at the example below and let me know your thoughts. I tried cooling it down and moving the hue in post and couldn’t get the skin right. Usually Canon nails skin so I am frustrated.

Is that after your corrections or before?

Before.

I think this not the fault of the camera but user error on my part.

White Balance affects the Kelvin setting (the yellow-blue axis of the color chart) but not the green-magenta axis.

I used post processing and sampled the white area at the bottom of the subject's cup to assume this is a neutral toned area. This is the result...
