In CC3.3, I use headshot pro to create a character. At first the color of the head (except the face) is the same as the rest of the body.
Then, I fine tune morphs using 'activate image matching tool' and Re-Project Photo. No masks on. And repeat several times.
So far the body color is consistent with the head:


Then, I add a face mask (default even) with or without eyelid mask. In this step, somehow the color of the body neck and below becomes distinctly different from the head. I don't know why but this has happened to me several times now. 


I try manually changing 'Skin Color' to match the body color to the face, which is successful,
but then the head color (except face) becomes too different from the face/body color as follows:


Is this because I use an Asian photo in headshot?
Or is there some other reason for this?

In any case, please teach me how to get around this color mismatching problem.
Thanks in advance.
