“Scarlet” is the name of a brilliant red, strongly tinged with orange or yellow, that has been prized across cultures for its intensity and its association with lifeblood, imperial power, and religious sacrifice. The word descends from the Persian sāqirlāt via Latin scarlatum, originally referring to a high‑quality woolen cloth dyed with kermes insects, a costly process that made scarlet a colour of rank and ceremony long before modern chemical dyes.

Position on the Tree of Life

In the mystical schema of the Kabbalistic Tree of Life, Scarlet appears specifically on Path 27, the twenty‑seventh path that connects Hod to Netzach. That path is attributed to the Hebrew letter Pe (פ), whose literal meaning is “mouth.” Scarlet is the King Scale colour assigned to this path, a vivid fiery tone that complements the sober violet‑purple of Hod and the rich amber of Netzach, bridging intellectual analysis with emotional passion.

Astrological and planetary correspondence

The planet of Path 27 is Mars, the ancient god of war and the symbol of raw energy, forceful assertion, and the sanguine humour. Scarlet is the colour of Mars’s sphere—the red of iron in the blood, of iron weapons, and of the red desert that covers the planet’s surface. This attribution reinforces scarlet as the colour of vital, sometimes destructive, life‑force.

Historical context

Scarlet has been among the most symbolically weighted colours in the Western esoteric tradition. In the Book of Exodus, scarlet thread is used in the tabernacle curtains and the high priest’s vestments, standing alongside blue and purple as a colour of sanctity and atonement. In medieval heraldry, gules—the heraldic term for red—was synonymous with scarlet and denoted magnanimity and fortitude; the “scarlet cloth” of the old English sumptuary laws was reserved for the nobility.

In alchemy and later ceremonial magic, scarlet appears as the colour of the Philosopher’s Stone in its final, perfected state—the rubedo stage, when the Great Work turns red and the Stone is said to gain the power to transmute base metals. The 17th‑century alchemist Basilius Valentinus speaks of “the true and perfect red, which is called scarlet,” as the sign that the stone is ready. In the Golden Dawn system, which directly informs the 777 correspondences, scarlet is the colour of Mars and of the yetziratic path Pe—the mouth that speaks the word of creation, breathing life into the forms built in Hod and brought to passion in Netzach.

Esoterically, scarlet also echoes the “scarlet woman” of the Apocalypse (Revelation 17), clothed in purple and scarlet, sitting upon a scarlet beast—a figure that, in Thelemic interpretation adopted by Aleister Crowley, becomes the symbol of liberated sexual energy and the fiery, creative force of the universe. For Crowley, as expressed in The Vision and the Voice, the 27th Path’s scarlet is the colour of the creative word uttered with full force, the power that gives form to the formless.

In the table of Liber 777, the cell for 15 (Path 15) does not contain “Scarlet”; rather, Path 27 is the cell whose King Scale colour is Scarlet. It stands in the row indexed as 27, the scale column “The King Scale of Colour (y).” There it is recorded unmistakably: the colour name alone, without further qualification, as the precise value for that coordinate. This entry follows the pattern seen across the whole column—each path and sefirah receives one tincture in the King Scale, and for Path 27 that tincture is Scarlet, the hue of Mars, of the letter Pe, and of the mouth that speaks fire.
