The colors of scribe 1, 2, and 3 (or A, B, C) all each different. The text color of scribes 1 and 2 is brown and for 3 it is black.

Are you sure this isn't simply ultramarine blue (ground lapis lazuli) or azurite?

You can (of course) tell these apart by Raman spectroscopy:-

Ultramarine comes from a land far from the sea (why of course it does) - but did you know that the land in question was Afghanistan? :-)
