Voynich style herbs+text wrapping: BSB Cgm 728

[Koen G]

Yeah, that's what drew my eye to it, this plant was in eggyk's opening post. 

Note that the letters are rotated differently: in the VM they are standing up and stacked, while in Cgm 728, the whole word is rotated 90°CW.
In Cgm 728, another word is added, the unclear word starting "fa..." that's also added to yellow, resulting in a brown. So "yellow fa..." and "red fa..." are both brown shades.

In Cgm 728, just "rot" results in proper red. If "rot fa..." means some reddish brown, then the color we see makes sense. In the VM, however, it simply says "red" in a yellow stem above a brown root.

One hypothesis may be that the VM artist drew from a MS that already had color annotations and just took them on board, initially. These were then not followed in the painting stage [whenever that may have been, let's not turn this into another later painter debate]. If this hypothesis is correct, it would mean that the VM relied on a MS that was itself a copy with color annotations, which may or may not have been fully painted.
