I have indirectly heard of someone in a school (I think it's a yeshiva student) who is doing a research project on various medical conditions. She decided to discuss tzara'at and compare what the Torah describes and compare it with current research of similar medical and environmental conditions. (E.g. there is tzara'at that appears on the skin - (medical / biological) vs. the form that appears on vessels and houses (environmental)).
The Torah mentions various colors and shades in describing most of tzara'at. To better understand what this looked like, she was wondering if anyone has published illustrations on these various conditions. It could be either in book form or on-line. If you know of such sources, please post them.
While the student is focusing mainly on the skin forms (there are several mentioned), if there is a book that illustrates and discusses the vessel, clothing, and house forms, that would be a huge bonus.
