I'm late into this color thing, maybe someone else has already chimed in on
this.
My neighbor sees blues very differently than I do. She sees more purple in
them than I do.
I have worked with color blind people who see colors wildly different than I
do.
I have books from the same publisher whose color photos are different even
at a casual glance.
I've dealt with people who interpret color by how they smell.
And while it's really cool the fancy technologies available, as we saw from
other posts of similar subjects the money ain't available for many of our
projects.
But, keep on trucking. The road of interpretation is open for many
destinations.

Hi John
If you are simply interested in the range of glaze color in the British
refined earthenwares from circa 1770 - 1830 or so, you are more than welcome
to visit sometime and I can give you a two-hour overview of the variables
related to that issue before you begin your colorimeter recordings. While
George has spent many years researching that period, I have spent almost the
same amount of time documenting extant China glaze examples from this long
period of time to better understand the evolution of the decoration,
identify manufacturers, and understand stylistic changes.
Beyond our articles which George has given the references, the new books by
Lois Roberts are essential to anyone who is interested in the evolution of
China glaze. Science and machines have their place in analysis...certainly
no one uses XRF and other techniques more than I do for ceramic research
issues...but the basic techniques of connoisseurship-the experience that
comes from hands-on observations also have a place. Sadly, these more
intuitive approach are rarely included in today's archaeological curricula.
Some snaphots of these "snowflakes" (that is, no two alike) may be of some
use:
http://ceramicsinamerica.blogspot.com/2012/02/color-variation-in-british-china-glaze.html
Please note these selected examples represent approximately 50 years of
British ceramic production, numerous manufactures and every example pictured
(there are many, many more) has a slightly different color.
