Smoky Lapwing

#0f3566
Notes

Smoky Lapwing (#0F3566) is a deep azure 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 (214°, 74%, 23%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smoky
adjective

An adjectival form of smoke, used as a color word since at least the fourteenth century. Smoky implies a slightly muted, slightly hazed quality — as if the color were seen through a layer of suspended particulate. Used across both deep and neutral buckets: a smoky black has slightly less density than pure black; a smoky gray has slightly less coolness than pure gray.

Lapwing
noun

The genus Vanellusplover relatives — particularly V. vanellus (northern lapwing), whose males display iridescent blue-black plumage on back and crest. The color refers to a male northern lapwing in breeding plumage: a saturated, slightly cool dark blue-green with the iridescent satin finish of structurally colored feathers.
