Tekhelet ( ) is a blue dye that historically held great significance in ancient Mediterranean civilizations. It is mentioned in the Hebrew Bible and is accordingly commonplace in Jewish culture, wherein it features prominently to color the fringes (called tzitzit) of several Jewish religious garments, such as the tallit. The dye was similarly used in the clothing of the High Priest of Israel and in tapestries in the Tabernacle.
