All I can say or put out there what my experience is.  I've had about 4
bathces of Piezo 4 oz. bottles.  All were about the same color.  I used a
CIS but then stopped when my densities started to vary too much.  I now load
Peizo into carts.  I've never, however, had the "green" or other problems
with it to the extent many seem to report on the Piezo list.  So, overall,
I've assumed that my Piezo experience is rather normal.

That said, I do consider the native color of Piezo to be slightly green, and
I do believe that the EAM print that I scanned, and the image I posted is
representative of my Peizo experience.

Paper type certianly does affect color.  Somerset Enhanced is warm.  EAM
I've always considered relatively neutral, but it does have about 1 unit of
green in the paper base according to my scanner.  Somerset Velvet has always
been the non-caoted paper that poepel point to as totally neutral.

Well, my Piezo on Somerset Velvet is certainly less warm than Piezo on EAM,
but the greeness is the same.  Although I did not have exact copies of
prints to compare, here are my RGB reading for EAM and Somerset Velvet with
Piezo ink:

EAM: RGB = 126/130/121

Somerset Velvet: RGB = 145/147/142

So, that is the best evidence I have.  Take it for what is it worth.  I
think the native color of Piezo is slightly green.
