[Cob] Dung doesn't color the plaster

[ocean]

The finish plasters are the color of the clay, which is either brown, 
yellow, or the beautiful red clays of our Oregon coast range (lots of 
ferrous oxide in the clay due to the iron content of the volcanic 
basalt).  Even though the dung can be dark black, once mixed into the 
clay slip/sand mixture the clay dominates the color.

We've found this to be true even if the plaster sits around in a bucket 
for awhile (weeks!) and darkens in color.  Once dried, it lightens up 
to the color of the clay.
