Or maybe I got that turned around backwards, that in slow-light
experiments
and if a Doppler shift effect existed with EM waves, that the slowed-
light
would become more bluer and bluer as it was slowed and slowed down.

But since slow-light is neither blueshifted nor redshifted, signifies
that
no Doppler shift effect exists.
