Crisp Pulsar Verdigris
Crisp Pulsar Verdigris (#3AA9AA) 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 (181°, 49%, 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
Latin crispus, curled — drifted in English from the curled hair sense to fresh and clean. As a color modifier, crisp implies saturation combined with optical clarity, with no haze or film between the eye and the surface. Used across the bright and crisp buckets where the hue is fresh-looking. Slightly less assertive than vivid.
Coined 1968, pulsating-radio-star. As a color modifier, pulsar implies a rotating-neutron-star-and-pulse-beam quality, the visual register of Crab-pulsar-and-Vela-pulsar hand-rotating-neutron-star-and-pulse-beam Crab-pulsar-and-Vela-and-PSR-1919 pulsar-and-rotating-neutron-star-and-pulse-beam surfaces under Crab-pulsar-and-Vela-and-PSR-1919 millisecond-and-radio-and-X-ray neutron-star-light. Sits at the modifier-and-cosmic end of the grid, parallel to nova and mira 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.
