Sylvan Curlew

#1f042a
Notes

Sylvan Curlew (#1F042A) is a deep violet 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 (283°, 83%, 9%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sylvan
adjective

Latin silvānus, of-the-woods — adjectival suffix -an, derived from silva (forest). As a color modifier, sylvan implies a neutral-and-forest-and-woodland quality, the neutral color of English-and-Welsh deciduous-and-mixed-forest woodland-walking-and-ramble pastoral-and-natural color tone. Sits at the neutral-and-traditional end of the grid, parallel to bucolic and pastoral in usage.

Curlew
noun

Eurasian Numenius arquata — a Scolopacidae shorebird of European-and-North-Asian estuaries-and-grasslands, with deep-mottled-brown-gray plumage and a long down-curved bill. Curlew color refers to a Numenius arquata dorsal-feather field in autumn-overcast light: a dark cool-gray with the matte finish of melanin-and-buff-dorsal-stripe structurally-colored feather barbs.
