But do you think that, for example, the hue shift towards a 'slightly greenish brown' of caucasian skin tones when viewed from an angle and in the shadow is really caused by cross-talking?

Brown isn't a hue. There's a green hue shift, and something else. What is that something else? Luminance? Desaturation?

Measure the skin tones in Photoshop in CIELab. Make the skin tones look right. Then measure again. Post the two sets of CIELab values.

When you say at an angle, do you mean that the lens axis is not orthogonal to the person's skin? Maybe you should post an example photograph.

Shadows are usually bluer than sunlit areas, because they are lit by the sky.
