Dark greenish brown is a color of profound depth and concealment, a hue that suggests the fertile decay of the forest floor, the rich soil from which life springs, and the hidden, subterranean currents of being. It is the color of the chrysalis, of the seed buried in the earth, and of the alchemical nigredo in its most fecund aspect. The term itself points to a synthesis: the green of growth and life force, tempered and darkened by the brown of earth, death, and stability, resulting in a color that is both vital and somber, promising and secretive.

Position on the Tree of Life

This color corresponds to the 18th Path of the Tree of Life, which connects the Sephirah Binah (Understanding) to the Sephirah Geburah (Severity). This is the path of the zodiacal sign Cancer, the Crab, and its associated Tarot trump, The Chariot. The dark greenish brown reflects the hidden, nurturing, and protective nature of Cancer, as well as the formidable, armored strength of the Charioteer. It is the color of the deep, mysterious waters from which all life emerges, and of the hard, protective shell that guards the tender life within.

Historical context

The use of dark greenish brown as a specific color correspondence in the Hermetic Order of the Golden Dawn and later in Crowley's work is not arbitrary. It draws from a complex system of color scales derived from the Sepher Yetzirah and later synthesized by MacGregor Mathers and others. In the Queen Scale (the scale of colors attributed to the Sephiroth in the world of Yetzirah), the color for the 18th Path is a dark greenish brown, a color that is also associated with the element of Water in its most material and formative aspect. This color is not found in the simple rainbow spectrum but is a compound, earthy tone, reflecting the path's position bridging the supernal abyss (Binah) with the realm of force and judgment (Geburah). It is the color of the 'Mighty Waters' of creation, the Tehom of Genesis, which are both dark and fruitful. In alchemy, this color appears in the early stages of the Opus, the putrefactio where the base matter blackens and begins to take on a greenish tinge, signifying the first signs of life within the decay.

Dark greenish brown appears in Liber 777 as the specific color for Path 18 in the Empress Scale of Colour, a scale that represents the most material and manifest expression of the divine attributes. It stands in stark contrast to the brighter, more fiery colors of the paths above and below, marking this path as a point of deep, hidden, and transformative power.
