This is the only shot from babysitting today where the skintones were all off. I was shooting in iAuto so the camera made the decisions. 1/500 sec at f5.6 ISO 250. Colours in the rest of the shots were fine.
I would say... not only WB: looks like the camera saw all that green and adopted some color saturation dedicated to panorama shots. Lowering the saturation helps, but the green on the face is due also to reflection (his skin is wet, green everywhere...). Must say it'd need some local retouching (sponge or similar) to clean the chin.
