Hygienic Pith Verdigris

Greek hygieinós, healthful — derived from Hygieia (goddess of health). As a color modifier, hygienic implies a clear-and-medical-clean quality, the crisp color of Mid-Century-Modern clinical-and-hospital interior-architecture surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and sterile in usage.

Old English piþa, pith / inner-stalk. As a color modifier, pith implies a soft-inner-stalk-or-core quality, the visual register of bamboo-and-elderberry-and-rattan-pith hand-cut-and-extracted soft-inner-stalk-or-core hand-cut-and-extracted-pith-and-core surfaces under hand-cut-and-extracted-pith-and-core workshop-light. Sits at the modifier-and-texture end of the grid, parallel to cane and bark 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.
