Nigredo, or blackness, in alchemy means putrefaction or decomposition. The alchemists believed that as a first step in the pathway to the philosopher's stone all alchemical ingredients had to be cleansed and cooked extensively to a uniform black matter . In psychology Carl Jung interpreted nigredo as a moment of maximum despair, that is a prerequisite to personal development . Further steps of the alchemical opus are albedo (whiteness), citrinitas (yellowness) and rubedo (redness).
