No text, but a visual code

[Barbrey]

The idea that the author painted the plants blue because he had an excess of blue paint seems to me a very poor explanation that ignores the medieval mentality.

  It seems much more plausible that the blue color in the flowers has a strongly symbolic component and that the author used it to relate the plants to the sky. In fact, the codex can be characterized as a herbal accompanied by astronomical or astrological sections, which reinforces the symbolism of the color blue. On folio f68v, in the middle of a circular diagram full of stars, we see in the center the corolla of a flower with blue petals.

   I've seen that you've started a thread about a possible anatomical interpretation of Quire 13, where there would be all kinds of human organs. This interpretation is a widespread error. And it's not a minor error, but a major one that demonstrates a lack of understanding of medieval iconographic representation.

I agree - the colour symbolism of blue, yellow, green and white (where it’s been painted but that’s very hard to tell sometimes) is very consistent in my schema despite the general sloppiness of the colorization. The only colour that I find difficult is red (or orange) which seems to be missing sometimes where it should be used, such as for fire. Instead we get a ring showing fire shapes around a few spheres but they’ve not been colored in. There will be a reason for this. I’ve thought of a few but no evidence to back up so won’t explain here.
