Behind the Craft

Watch Tyrian Purple Being Made

A rare window into the ancient process — from Murex sea snail to imperial pigment, in Mohamed's hands.

The Pigment

What is Authentic Tyrian Purple?

Tyrian purple — also called royal purple or imperial purple — is the most historically significant colorant ever produced. Genuine Tyrian purple is derived exclusively from the hypobranchial gland secretions of Murex sea snails (Bolinus brandaris and Hexaplex trunculus) found in the Mediterranean Sea.

The chemical compound is 6,6′-dibromoindigo — a molecule creating the characteristic deep crimson-purple with extraordinary lightfastness. This is the identical pigment that clothed Phoenician merchants, Roman consuls, and Byzantine emperors, described by Pliny the Elder as having the color of clotted blood that "gleams with a dark richness."

The knowledge was largely lost after the fall of Constantinople in 1453. Mohamed Ghassen Nouira of Argaman, Tunisia has recovered and mastered this process — and Empyrex is his exclusive North American partner.
