In another thread, Marco referred to McCrone's report about the blue ink:

I selected some blue surfaces from the large plants (first 20 or so folios). Each clip is from a different folio. As you see, there are a few ways in which the blue paint looks off. Sometimes there are dark spots, and often something yellowish shines through:
What are your thoughts about this? Has anyone researched paint preparation before?
Is the blue-yellow a result of a suboptimal blend of different substances? Or is the yellow merely a result of a lighter blue wash with pen ink? Or are these the cuprite traces mentioned in the report?
Or - and this is where we enter Voynich territory - does the blue mask a color that was previously applied? While compiling this, I notice the ugliest blue is often found near yellow surfaces.
Similar things are found throughout the MS. Here's an example from the "white Aries" page. The top nymph has a light blue barrel where the wash seems mixed with yellow. The bottom one gets a relatively even blue, in quality not worse than the red of her dress.
