Sinewy Lapwing
Sinewy Lapwing (#1158CF) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (218°, 85%, 44%) places it in the highly saturated band at a mid 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English sinu, sinew — adjectival suffix -y. As a color modifier, sinewy implies a saturated-and-muscular-and-firm quality where the hue carries the lean-and-strong visual presence of a Roman-statue athletic figure. Sits at the bold-and-firm end of the grid, parallel to stalwart and rugged in usage.
The genus Vanellus — plover 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.
