Do Herbal A and Herbal B correspond to differences in imagery?

[MichelleL11]

[The B scribe was short of red paint, as opposed to the A scribe.

The latter observation is important, because it shows that the scribes worked separately from one another, that is - not at the same location.

As much as I would greatly enjoy being able to make any kind of conclusion like this about the VM production, I have to disagree that this is what naturally follows from Currier A pages having a fair amount of red paint and Currier B pages having little to no red paint.  Different locations (with differing red paint availability) is certainly a possibility -- but it is one of many.

Other possibilities than "separate working locations (e.g. "red paint only in one location theory"):

1.  All painters involved worked in the same location, but there was only so much red paint and it was all gone by the time Currier B pages were done (perhaps the bottle got knocked over?) -- and no more was available and/or the project had run out of funding such there was no more money to buy more (e.g. "red paint amount or funding limiting" theory).
2.  The painter for Currier A loved the color red or the painter for Currier B pages didn't like red (e.g. "painter prerogative theory", if more than one painter -- keyed to Currier A and B) or the same painter became "disenchanted" with the red paint over the course of the project (if A truly came before B).
3.  Plants actually having red leaves, berries, roots were specially selected to be on the Currier A pages (for a possible variety of unknown reasons) ("Plants with actual red parts were purposely placed on Currier A pages" theory - maybe plants were produced in some sort of "favored" order by the painter and they really liked red?).  
4.   The use of the red hue has some sort of symbolism (e.g. are not reflective of any particular plant) that is more appropriate for the plants illustrated in Currier A (e.g. Currier A selectively illustrates those plants that treat blood/menstrual related issues, etc).  Could also throw in the whole "red roses" thing, perhaps -- although I believe that is Lancaster rather than York . . .
5.   Only one painter did all possible red (e.g. like the scribe "You are not allowed to view links. Register or Login to view." specialists, maybe "owned" the red paint) and that painter died, was imprisoned, left the project, etc. before getting to Currier B pages ("red painter unavailability theory").  Maybe the several possible unpainted-over "rot" or "r" symbols even in Currier A are the result of this?

Eh, that's enough -- understand, Anton -- I get what you're saying, but I just can't get on board with your conclusion as a necessity.
