argaman or
tekhelet in Hebrew, is a particularly vibrant hue mentioned only a few times in the Bible, when describing drapings for kings, a carriage for King Solomon, the tabernacle in Exodus, and for coloring tzitzit, the fringed garment still worn by many observant Jews.
But while purple was clearly a holy color, we didn’t really know what it looked like until now. In the Timna Valley in Israel, scholars have discovered a scrap of purple-dyed fabric from 1000 B.C.E, the era of Solomon and David, Israelite kings who were adorned in the color; their findings were published in the journal PLOS ONE.
