The concentration of the cholorphyll is in the palisade mesophyll--which is arranged closer to the topside of the leaf structure--may account for some of the color differences. Recall that the top is the surface that will be gathering light energy, hence chlorophyll positioning would mean a great deal.

The palisade mesophyll is labeled F in the image from navin.

No, they are not. As ERS said, there is more chlorophil in the palissade tissue
