Hello geujfys and welcome to the forum! I have seen your post on the VMs subreddit and submitted a short comment there, in the same line as Anton. Point B is specially important: we cannot be sure about what colours, if any, the author/authors had in mind when they wrote the text.
However, there has to be a word in voynichese for "figure": The author needs a way to point to illustrations ("As we can see in this figure..." "This figure depicts..."), unless one believes that the text and illustratios are not related at all.
I had this thought after discussing the Tratado de Astrologia (You are not allowed to view links. Register or Login to view.) in a previous thread. In this MS the author uses the world figure (spanish figura) extensively when there are illustrations in the page.
Might be a very "broad" term to look for, though. But in the same line of your method. Maybe more experienced researches can provide more useful feedback to you.
