Imperial purple and sacred blue.
Once upon a time, among all the colors, 2 were the most valuable.
The Imperial purple and the sacred blue.
These colors were so valuable that you had to pay their weight in gold to buy them.
Both dyes extracted from sea snails known as Murex. Lots of people had to work hard to produce these dyes. While a whole nation (Phoenecians) became rich and famous for selling them.
This is also known as Royal purple, Tyrian purple, Tyrian red, porfyra (πορφύρα) in Greek and purpura in Latin.
The dye was a symbol of power at least since 3.500 BC. It was so expensive that only kings, emperors, popes and cardinals could afford it. As estimated, 12.000 snails needed to extract only 1,5 gramms of dye.
A myth says that the purple dye was first discovered by Heracles. Or rather, by his dog, whose mouth stained purple from chewing on snails along the coast of the Levant.
Its production discontinued when Muslims conquered the Byzantine empire. The know how is now lost. But anyone will show you the right sea snail if you ask about porfyra.
Tekhelet - the sacred color of Hebrews.
Tekhelet (Hebrew: תכלת təḵêleṯ, "blue-violet", or "blue", or "turquoise" is a blue dye mentioned in the Hebrew Bible/Tanakh.
In the Septuagint, tekhelet translated into Greek as hyakinthos (ὑακίνθος, "hyacinth").
Used in the clothing of the High Priest, the tapestries in the Tabernacle, and the tassels (Tzitzit). Such as the Tallit (garment worn during prayer, usually).
