Tekhelet
While roaming the internet looking at obscenely high priced murex pigments, I found this site, describing how dibromoindigo of the murex trunculus snail becomes indigo in uv light, thus arguing that it is in fact the tekhelet of Torah.
I just wanted to share a site that puts the Bible and dyeing together-all the things I like! AAAHHHH-I think my head just exploded.
