The note unfolds with a distinctive metallic sheen, cool and almost sharp, reminiscent of the tempered steel of a pen nib. This is immediately followed by a profound, inky accord: a rich, dark cyan or indigo hue translated olfactorily, with subtle facets of ozonic freshness, a whisper of slightly dusty paper, and a refined, subtly sweet, almost phenolic quality that speaks to the specific dyes and solvents in the ink. It possesses an elegant dryness, a refined crispness that prevents it from ever becoming heavy or cloying. The intensity is moderate, projecting an intimate, cerebral aura. It evolves slowly, with the initial metallic glint softening into a more integrated, persistent ink-and-paper embrace. Its longevity is remarkable for such an ethereal concept, often anchoring itself as a nuanced heart-to-base accent, providing an intellectual backbone to a composition.
