Bucolic Belfry

#1d0735
Notes

Bucolic Belfry (#1D0735) is a deep indigo 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 (269°, 77%, 12%) places it in the highly saturated band at a dark 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bucolic
adjective

Greek boukolikós, of-cattle-herding — adjectival suffix -ic. As a color modifier, bucolic implies a neutral-and-rural-and-pastoral quality, the neutral color of Constable-Stour-Valley-painting and Beethoven-Pastoral idyllic-rural-pastoral mood-evoking color treatment. Sits at the neutral-and-traditional end of the grid, parallel to pastoral and idyllic in usage.

Belfry
noun

Old French berfroi, protective-tower — the deep-cool-gray fortified-tower bell-housing of medieval-and-Renaissance European parish-and-cathedral-and-civic-architecture. Belfry color refers to a Bruges-Belfort 13th-century belfry-tower face in November-overcast light: a dark cool-gray with the matte finish of Tournai-bluestone hand-quarried Carboniferous-limestone in 84-meter-tall hand-built civic-tower.
