No text, but a visual code

For these authors, the naked women could represent the soul of the plant, and the green color, the sap flowing through the plant's vessels.

What I find particularly interesting is the question of the green fluid. Your reference to Hildegard of Bingen’s viriditas opens up a much broader possibility of interpretation than simple plant physiology. For me, this leads to a rather extraordinary association with The Matrix, the film by Lana and Lilly Wachowski.

Let me present my perspective on it, actually a very mundane one.

The water in Voynich Manuscript is green probably because it was so in De Balneis Puteolanis and was copied from it:


And why was it green in De Balneis?
Because it was the style of Petrus de Eboli, the man who made De Balneis. The original of De Balneis is lost but we have another book of him, Liber ad Honorem Augusti where he uses a very limited palette of colours, with lot of green. We can assume the original De Balneis was also made this way which was then reproduced to most copies of it:


Matrix, one the other hand, has green letters running because early monitors often had monochrone green display and this is a referrence to it. And they had green display due to technical reasons because they flickered less this way. You can google the detail if you want.

So I would say green colour in both Voynich Manuscript and Matrix are both a bit random events and I wouldn't seek for any deeper, especially spiritual meaning in it.
