Pleasant Plasma Verdigris

From the French plaisant, pleasing — used as a color modifier since the fifteenth century for hues that read as agreeable, the kind of color that wears well over a long viewing without becoming demanding or fatiguing. Pleasant green, pleasant rose: moderate saturation combined with optical comfort. Sits at the crisp-bucket alongside easy and calm.

Greek πλάσμα, something-molded-or-formed. As a color modifier, plasma implies an ionized-and-fourth-state-and-stellar-glow quality, the visual register of solar-corona-and-fluorescent-plasma hand-ionized-and-fourth-state-and-stellar-glow solar-corona-and-fluorescent-and-neon-tube plasma-and-ionized-and-fourth-state surfaces under solar-corona-and-fluorescent-and-neon-tube laboratory-and-stellar-and-aurora ionized-glow-light. Sits at the modifier-and-cosmic end of the grid, parallel to corona and nova 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.
