Does it not just get bluer falling in gravity. The higher the
frequency, the more energy a photon has.

"Photons climbing out of a gravitating object become less energetic. This
loss of energy is known as a "redshifting", as photons in the visible
spectrum would appear more red. Similarly, photons falling into a
gravitational field become more energetic and exhibit a blueshifting. The
observed energy E_observed at radius r_observed of a photon emitted at
radius r_emitted with energy E_emitted is [7] "
