Do you mean my eyes are not calibrated? It is true, my spectro was 
calibrated, and I don't think numbers are wrong. What I was trying to 
tell is paper with cooler tone looks more "white", which is supported 
by the measurements.

Well, I don't agree with that. I spent a lot of paper and inks trying 
to get good QTR profiles without using spectro -- and without 
success. Eyes doesn't help a lot in this process. Scanner, by the 
way, doesn't help either, even profiled scanner.
