No, it can't. The speed of light is the speed of light. BUT...as regular
objects fall they will speed up gaining kinetic energy. So following along
these lines I would say light will gain energy as well, which will manifest
itself as a blue-shift. (Higher energy = higher frequencies = bluer light).
Actually, the light may not really change frequecies (or, rather, wavelengths)
at all. Instead, the mass of the black hole may distort space such that more
light waves would fit in the "stretched out" space. (Pictures this: you lay a
rubber band next to an erase and see one eraser fits in the band. Now stretch
the band; suddenly you can fit three. Something along these lines...)
Cool question.
