Symmetrical Hour Verdigris

Greek symmetría, due-proportion — adjectival suffix -al, derived from sym-metron (with-measure). As a color modifier, symmetrical implies a clear-and-balanced-and-mirrored quality where the hue carries the visual register of bilateral-or-radial proportional symmetry. Sits at the crisp-and-balanced end of the grid, parallel to balanced and aligned in usage.

Latin hōra, time-of-day. As a color modifier, hour implies a single-time-period quality, the visual register of Edwardian-and-Victorian household clock-marked single-hour-of-the-day domestic-and-formal interior surfaces under hour-by-hour pendulum-clock day-light. Sits at the modifier-and-time end of the grid, parallel to bell and vesper 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.
