Different color discrimination

[tivol at tethys.ph.albany.edu]

Mark Siddall writes that his eyes sense color slightly differently.  I have
noticed this also; furthermore, closing one eye for a while can shift the
perception so that the more magenta eye becomes the less magenta eye.  There
are, undoubtedly, many of this kind of phenomenon which can be explained by
the details of visual perception.
