Bucolic Falcon

#171f2a
Notes

Bucolic Falcon (#171F2A) is a deep azure 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 (215°, 29%, 13%) places it in the muted 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 amber. 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.

Falcon
noun

Cosmopolitan Falconidae family — raptors of open-country habitats with deep-glossy-bluish-gray dorsal-plumage, particularly the Peregrine falcon (Falco peregrinus) of urban-cliff-and-rural-cliff nesting. Falcon color refers to a Falco peregrinus female adult dorsal-feather field in raking light: a dark cool-gray with the glossy finish of melanin-pigmented raptor-feather barbs over melanin substrate.
