What colour is Tyrian purple?
Tyrian purple is a strong reddish-purple dye, most often linked with the robes of ancient royalty and high officials. Its colour ranges from a deep blue-purple to a shade like dried blood, depending on how it is made. Unlike many other ancient dyes, Tyrian purple does not fade easily and can even become brighter with age and sunlight. It stands out from other purples for its origin in sea snails and its long history as a luxury item.
Where does Tyrian purple come from?
The name comes from Tyre, a city in ancient Phoenicia, now in Lebanon, where the dye was first made. The process began as early as 1570 BC, possibly even earlier, and spread through Phoenician trade. The dye's rarity and difficulty of production made it a symbol of power. In Rome and Byzantium, laws restricted its use to emperors and top officials. Legends say the dye was discovered when a dog bit into a snail and stained its mouth purple.
How is Tyrian purple made?
Tyrian purple is made from the hypobranchial gland of several species of murex sea snails. To extract the dye, thousands of snails were collected and either milked for their secretion or crushed. The process involved soaking the glands, adding salt, and boiling the mixture for days, then dipping wool or cloth into the liquid. The colour develops through exposure to air and sunlight, and the best results depend on the freshness of the snails and careful timing.
Where Tyrian purple is used
This dye was mainly used for colouring textiles, especially garments for royalty, priests, and high officials. In ancient Rome, only the emperor could wear clothing dyed entirely in Tyrian purple. The dye was also used in ceremonial robes and sometimes in art. Its production left behind large piles of snail shells, which have been found at archaeological sites around the Mediterranean.
What Tyrian purple means
In ancient societies around the Mediterranean, Tyrian purple stood for royalty, power, and sacredness. Because of its cost and the effort needed to make it, only the wealthy or those with high status could wear it. In Rome and Byzantium, it became a mark of imperial authority, and being 'born in the purple' meant being born to the emperor. The link between purple and royalty in many cultures comes from this history.

Other dyes from related snails could produce shades from blue to violet. The most prized Tyrian purple was a dark, almost blackish-red. Cheaper imitation purples were made from other materials, but they lacked the lasting quality of true Tyrian purple. Sometimes, cloth was double-dipped in different snail dyes to achieve deeper or more complex shades.
