Quiet Bay
Quiet Bay (#187783) is a deep cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (187°, 69%, 30%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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 quietus, at rest — used as a color modifier since the medieval period for hues that read as restrained. Quiet pink, quiet blue: low saturation combined with optical calmness. Sits across the crisp and hushed buckets where the color is present but doesn't ask for attention.
A body of water partially enclosed by land — Chesapeake, Tokyo, Hudson, Naples. The color refers to the average reflectance of a temperate bay on a clear day: a saturated, slightly muted blue with the optical depth of mid-salinity water. Cooler than peacock, warmer than navy, with the geographic specificity of a word that names the largest indentations in every world coastline.
