Red snow and green

Now I am puzzled.  I learned many years ago from a snow algologist friend
that the red pigment was a hematochrome.  I don't have the biochemistry
background to know if astaxanthin is a hematochrome, or vice versa.  Has
our understanding changed, or are we talking about more refinement of
naming it?  Since I teach about this organism, I would like to know if I
am wrong.
