"In the Bible, a shade of blue called tekhelet was God’s chosen color for the ancient Israelites. Tekhelet drapes adorned Solomon’s Temple, and tekhelet robes were worn by Israel’s high priests.
Israelites “were commanded to tie one string of tekhelet to the corner fringes (Hebrew, tzitzit) of their garments as a constant reminder of their special relationship with God” (Numbers 15:38–39). The tradition of blue tzitzit still exists today.
But what was the actual color of ancient tekhelet and blue tzitzit? Was it a shade of blue or was it closer to purple? Blue tzitzit and tekhelet-colored fabrics were widely worn and traded throughout the ancient Mediterranean, but by the Roman period, only the emperor could wear tekhelet.
A century ago, Isaac Herzog, who would later become Israel’s first chief rabbi, researched tekhelet for his dissertation. He concluded that blue in the Bible was a bright sky-blue derived from the secretions of a sea snail, Murex trunculus. This species was known to produce a murex dye the color of dark purple. Decades after Herzog’s death, chemist Otto Elsner proved that murex dye could in fact produce a sky-blue color by exposing the snail secretions to ultraviolet rays during the dyeing process. Sky-blue tzitzit, then, could be made with murex dye." BiblicalArchaeology

Speak unto the children of Israel, and bid them that they make them fringes in the borders of their garments throughout their generations, and that they put upon the fringe of the borders a ribband of blue: And it shall be unto you for a fringe, that ye may look upon it, and remember all the commandments of the LORD, and do them;
That ye may remember, and do all my commandments, and be holy unto your God.
Numbers 15:38-40
