Placid Ignis Verdigris

Latin placidus, gentle / quiet — derived from placēre (to please). As a color modifier, placid implies a clear-and-unruffled quality where the hue carries the visual register of mirror-smooth lake-surface in windless mid-morning. Sits at the crisp-and-calm end of the grid, parallel to serene and peaceful in usage.

Latin ignis, fire. As a color modifier, ignis implies a Latin-fire-and-ignis-fatuus-and-sacred-fire quality, the visual register of Vestal-fire-and-ignis-fatuus hand-Latin-fire-and-ignis-fatuus-and-sacred-fire Vestal-fire-and-ignis-fatuus-and-Roman-Vesta-temple ignis-and-Latin-fire-and-Vestal-flame surfaces under Vestal-fire-and-ignis-fatuus-and-Roman-Vesta-temple Vestal-Virgin-and-Forum-Romanum sacred-flame-light. Sits at the modifier-and-Latin end of the grid, parallel to lux and ventus in usage.

The basic copper carbonate that forms on weathered copper and bronze — the pigment scraped from oxidized metal and used in Renaissance painting before being supplanted by more stable greens. The color refers to a thick verdigris on aged copper roofing or the Statue of Liberty's surface: a soft, slightly muted blue-green with the powdery finish of mineral oxide. Cooler than patina, warmer than seafoam, with the archaeological weight of a mineral made by time.
