No text, but a visual code

[Antonio García Jiménez]

Are the colors used in the Voynich significant? Do they serve to interpret the images iconographically? 

Apparently, the colors do not surprise us. We see green predominate in the herbarium, blue in the cosmological pages together with yellow for the stars, and ocher for the roots in the so-called pharmacological section.

The biggest problem of interpretation is in Quire 13, the one with the misnamed nymphs. Here we see blue and green, the blue mostly at the top of the page which, together with the wavy lines simulating clouds and structures that represent ceilings, lead us to think that the female figures come down from the sky. We see green not in the tubes, but in the bulges or pools. The impression is that the liquid is water. It could be, but Mary d' Imperio pointed to another interpretation.

She described the similarity between the plumbing in the section of female figures and the way the roots and stems are drawn in the herbarium and noted the following:
  
  Some form of humor, essence, moisture or sap seems to be of primary importance in the doctrine expressed by these pictures

What magnificent insight! 

The green color may represent the sap of herbs, which links all sections of the book
