"...Any chance you are over 50? Cataracts often effect print viewing 
color before they affect screen color, unless you are using proprely 
bright, hight CRI D50 proofing lights..."

I had a cataract in my right eye and a few years ago had it removed 
and a new (plastic) lens inserted.  On returning to the doctor for a 
check up, I commented on the color cast difference between my right 
and left eye, with the left having a distinct yellow cast.  

His comment was that I should "believe" the right eye.  He went on to 
say that as we age the lenses turn yellow-ish with age.  I now to all 
my final color judgements with my right eye <G>.
