Citrinitas (Yellowing)

Citrinitas is the third stage of the Magnum Opus, the yellowing that bridges the white stone of albedo and the red stone of rubedo. The purified matter begins to take on solar qualities — an internal luminosity that the adepts called the 'dawning of the gold.' Many later alchemists, following the Turba Philosophorum, collapsed the four-stage model into three and dropped citrinitas entirely. Where it is preserved, it marks the transition from lunar receptivity to solar radiance — the substance generating its own light rather than merely reflecting.
