Fresh Brine Verdigris
Fresh Brine Verdigris (#39AAA0) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (175°, 50%, 45%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.
Old English brȳne, salt-water-or-pickle-brine. As a color modifier, brine implies a salt-water-and-pickle-and-tide-pool quality, the visual register of Atlantic-tide-pool-and-pickling-brine hand-salt-water-and-pickle-and-tide-pool Atlantic-tide-pool-and-pickling-brine-and-Cornish-rock-pool brine-and-salt-water-and-pickle surfaces under Atlantic-tide-pool-and-pickling-brine-and-Cornish-rock-pool Lizard-Point-and-North-Cornish-coast salt-tide-pool-light. Sits at the modifier-and-weather end of the grid, parallel to floe and torrent 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.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
