Placid Vela 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 vela, sails-of-the-Argo. As a color modifier, vela implies a southern-hemisphere-and-Argo-sail-and-supernova-remnant quality, the visual register of Vela-supernova-remnant-and-Argo-sails hand-southern-hemisphere-and-Argo-sail-and-supernova-remnant Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way vela-and-southern-hemisphere-and-Argo-sail surfaces under Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way Southern-Cross-and-southern-zenith southern-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to cygnus and draco 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.
