I had a look at the portrait posted.

First i took two patches laid over each other with light and shadow Lab values, second I did the same but using the same L value. Here is a screen dump:

Here is the JPEG. Note how much the screen dump distorts the colors

Looking at the Hsv coordinates the hue change would be on the red/yellow segment.

Just to say, it is a nice portrait and I like the colors.

Best regards

Thanks for looking closely.

That's what Jim said (shift toward yellow).

That's what I see with the patches superimposed.
Thats' not what I see in the actual picture, at least in some areas (in paricular below the lips). It looks like the brown has 'a greenish cast'.
Some say it maybe a color contrast effects.
