A new area of learning.
Just thinking about parchment is bad enough; but I think I can manage some inks.
The blue is woad.
The green is verdigris (I dont like this; can be acidic and might eat through the parchment in a few hundred years)
The white is alum (and not chalk, as I assumed)
Purple is lichen, but WHAT lichen???
Red is lead oxide, (acceptable) and yellow Arsenic oxide (not) What about ochres?
Any suggestions? things to swap?
