Rediscovered, Ancient Color Is Reclaiming Israeli Interest
RAMAT GAN, Israel — One of the mysteries that scholars have puzzled over for centuries is the exact shade of blue represented by “tekhelet,” which the Bible mentions as the color of ceremonial robes donned by high priests and ritual prayer tassels worn by the common Israelite.

Though scientists and scholars are still debating the exact shade of the ritual blue, the dye used is modeled after a 2,000-year-old textile, above, and is produced from sea snails found in Israeli watersWhat was known about tekhelet (pronounced t-CHELL-et) was that the Talmud said it was produced from the secretion of the sea snail, which is still found on Israeli beaches.
