Purple occupies a distinctive but concentrated place in the depth-psychology corpus, functioning chiefly as a color-symbol of completed alchemical transformation and sovereign spiritual authority. The term clusters around three intersecting registers. First, in the alchemical literature mediated through Jung, Abraham, and von Franz, purple designates a stage or tincture intimately related to the rubedo: the dyeing of the purified white stone with a richly reddened purple hue signals the assumption of royal power — the king putting on the purple robe — and thus the integration of the lower self into the higher. Abraham traces this symbolism explicitly to Tyrian dye, the porphura of Greek etymology, and to the alchemical principle that Theophrastus compared the reddening of slain Mercurius in its own blood to the dyeing of a white garment in Tyrian purple. Second, in Jung’s indexed references across Psychology and Alchemy, The Practice of Psychotherapy, and Mysterium Coniunctionis, purple appears as a coordinate within the broader alchemical color series — alongside nigredo, albedo, citrinitas, and rubedo — marking a transitional or culminating chromatic stage with both cosmological and psychological valence. Third, in the Tarot hermeneutics of Jodorowsky, purple-violet stands as the color of the androgyne, positioned at the apex of a symbolic color hierarchy. Tensions emerge between purple as material sovereignty (the dark shade of political power) and as spiritual mastery (the amethyst light of self-transcendence), a polarity Joan Hodgson articulates with precision. The term thus traverses royalty, sacrifice, transformation, and androgynous wholeness.
