Unwavering Magpie

#1b5db8
Notes

Unwavering Magpie (#1B5DB8) 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 (215°, 74%, 41%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Unwavering
adjective

Old English un- (negation) plus wafrian (to flicker). As a color modifier, unwavering implies a saturated-and-constant quality where the hue maintains its full strength without flicker or shift. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm in usage.

Magpie
noun

The genus Cyanopica — Asian azure-magpies — corvid relatives of the Pica magpies but with saturated deep-blue plumage on back, wings, and tail. The color refers to a male C. cyanus (azure-winged magpie) wing: a saturated, slightly cool deep blue with the matte finish of structurally colored corvid feathers.
