The Great Work is conventionally divided into colour stages: nigredo (blackening), albedo (whitening), citrinitas (yellowing) and rubedo (reddening), though the yellow stage is often omitted in later accounts. The sequence describes the appearance of the material in the vessel and, in the tradition's own reading, the transformation of the practitioner. Carl Jung's twentieth-century treatment of these stages as psychological processes is influential but is an interpretation rather than the historical meaning.

The colour stages of the Great Work

The Great Work is conventionally divided into colour stages: nigredo (the blackening), albedo (the whitening), citrinitas (the yellowing) and rubedo (the reddening), though the yellow stage is often omitted in later accounts, leaving a three-fold black-white-red sequence. The stages describe the changing appearance of the matter in the alchemist's vessel as the work proceeds toward the Philosophers' Stone.

Nigredo is the initial breakdown and putrefaction, a dissolution into blackness; albedo the purification and washing that follows; citrinitas the dawning of a golden light; rubedo the final reddening in which the Stone is achieved.

Colour, Matter and Soul

As with the operations, the colour stages are read on two levels: the literal succession of colours in the flask, and the stages of an inner transformation, the death of the old self in the nigredo, its purification in the albedo, its perfection in the rubedo. The imagery pervades alchemical art and was taken up in modern times by Carl Jung as a model of psychological individuation.

The atlas gives each stage its colour, its process, and its symbolism. The operations that carry the work through these stages are treated in the alchemical-operation category, under Texts & the Canon.
