Color is always difficult.
There are some color tricks that can help you and the camera.
Many photo shops have a neutral gray reference card that
can be used as a reference for setting the color balance of
a photo or camera (white balance, color temp of light source).

If you place such a card in the back of the image most cameras
will get a true(er) color balance.

Slurry color is also another difficult topic. Work a slurry up
then swipe a smear of it across the back of a white 3,5" file card.
Again with much of the frame filled by the reference gray card.

Interestingly enough the paint cards at a paint store
can help separate subtle tones. If you find a store that
has a big display pick a fan of the gray, green gray, pinkish
gray samples. By lining a set of them up and comparing
to the hone you may better see the subtle differences.


This is hard stuff... The Geologic Society of America has a Rock Color Chart.
Google for "Munsell Rock Color Chart" but at $70 this
is not as accessible as the paint store color chips might be. This combined
with differences in perception makes a reference and systematic
naming very important. Another reference from the print world
may include Pantone color charts but they are weak on this class
of earth tones and also expensive.

It looks gray to me, IIRC they run from darker to lighter, smooth to smoother.
If that makes any sense.
