Scarlet red is the color of arterial blood, of living flame, of the raw and uncompromising force that drives action. Its etymology traces through Old French escarlate, from Medieval Latin scarlatum, a high-grade cloth, but in the magical lexicon, its meaning is far more primal: it is the color of Mars, of Geburah, of the active and terrible aspect of the divine.

Position on the Tree of Life

Scarlet red is the Queen Scale color of Geburah, the fifth sephirah. Geburah is the sphere of Severity, Strength, and Judgment, the force that balances the expansive mercy of Chesed. As the feminine, receptive (Queen) scale, this scarlet is the receiving vessel for the raw, active power of Geburah's male (King) scale, often represented by a complementary deep orange or fiery red. It is the color of the judgment that has been made manifest, the blood-spilt consequence of divine law.

Astrological and Planetary Correspondence

Scarlet red corresponds directly to the planet Mars. The astrological glyph for Mars (♂) is the shield and spear, and its color is the blood-red of the warrior. This is not the subtle, transformative red of the alchemical Ruby, but the stark, immediate red of combat, lust, and decisive action. It represents the raw, unrefined energy of the Chayoth ha-Qadesh (Holy Living Creatures) of Fire, the angelic order of Geburah.

Historical Context

The association of a specific shade of red with severity and war is ancient, found in Roman military standards and the war banners of various cultures. In the Hermetic Order of the Golden Dawn, the color scales for the Tree of Life were meticulously codified from a synthesis of Kabbalistic, astrological, and alchemical sources. The 'Queen Scale' (the third or 'feminine' scale) for Geburah was fixed as Scarlet Red.

In Aleister Crowley's Liber 777, this color is set in a vast table of correspondences. It is not a metaphorical color; it is a direct, energetic signature. When the magician visualizes scarlet red in ritual, they are not merely imagining a color—they are invoking the force of Geburah, the principle of harsh judgment, of severing, and of the victory that comes through righteous destruction. The use of scarlet in ceremonial magic (e.g., altar cloths, robes, implements) is to attract and anchor this specific, martial current.

In the Correspondences of Liber 777

In Liber 777, at the row for Geburah (XVI.*...), the Queen Scale of Colour is given as 'Scarlet red'. It stands in contrast to the blues of Mercy (Chesed) and the yellows of Beauty (Tiphereth), a stark reminder that the Path requires the flaming sword of discrimination.
