Digital BW, The Print

I just (re)opened a box of Hahnemuhle Photo Rag 308
that I haven't used since I printed Christmas
pictures last year. I loosely resealed the box and set 
it aside last December.

My recollection is that Photo Rag is virtually the same 
color as Epson Enhanced Matt. 

When I look at it now, however, it is distinctly warmer 
than EEM, a light creamy color. Not ugly, just warmer than
I expected. The warm tone is totally even on all sheets 
of the paper in the box. It doesn't look like discoloration, 
but on the other hand, I could swear it was closer to 
EEM-white when I first used it. But maybe I've just gotten 
too used to looking at EEM...

Could someone confirm that Photo Rag is indeed warmer 
than EEM? 

Thanks,
David
