That is not the point. The size, color, shape is
pointless to A person who cannot see. A screen reader
will read out the text  regardless of its color and
other attributes.
Hence it is a problem when one reads "fields  in red
are mandatory on the form". One can read the
instruction and the form field labels but may not be
able to tell the color difference. 
An asterisk or a word "required"  within the label
with a suitable instruction conveys the point. 
With regard to information v/s differences:
Sure we are talking about information conveyed by
color.
And information refers not only to semantics or
meaning but also structure.
But it is the variation in color  which is the key
that distinguishes some content from  some other 
content.
It is alright to do this too to reinforce the point
for the benefit of sighted users.
But it should be accompanied by suitable markup too so
that it is evident to one who cannot see.
eg. Sometimes grouping of data is conveyed visually by
color differences. The groups need to be marked up
suitably- headers, lists etc. may be an alternative.
