Heartening Flare Verdigris

#63f7ec
Notes

Heartening Flare Verdigris (#63F7EC) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (176°, 90%, 68%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Heartening
adjective

Old English heorte (heart) — present-participle of hearten. As a color modifier, heartening implies a clear-and-uplifting-and-encouraging quality where the hue carries the visual register of cheerful-encouraging color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and cheerful in usage.

Flare
modifier

Origin obscure, attested c. 1540, to-burn-with-an-unsteady-flame. As a color modifier, flare implies a sudden-and-spreading-and-bright-burst quality, the visual register of signal-flare-and-solar-flare hand-sudden-and-spreading-and-bright-burst signal-flare-and-solar-flare-and-magnesium-distress flared-and-sudden-and-spreading-and-bright surfaces under signal-flare-and-solar-flare-and-magnesium-distress shipboard-and-rescue-and-corona high-intensity-light. Sits at the modifier-and-mood end of the grid, parallel to blaze and flash in usage.

Verdigris
noun

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.
