Surveyed Chive Kingfisher

#1fa3b8
Notes

Surveyed Chive Kingfisher (#1FA3B8) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (188°, 71%, 42%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Surveyed
adjective

Old French surveer, to look upon — past-participle of survey. As a color modifier, surveyed implies a clear-and-measured-and-coordinated quality, the crisp color of Mason-Dixon-Line-and-Royal-Navy-Hydrographic scientific-and-cadastral land-and-sea surveying tradition. Sits at the crisp-and-mapped end of the grid, parallel to mapped and plotted in usage.

Chive
modifier

Latin cepa, small-onion-grass-herb. As a color modifier, chive implies a slim-grass-onion-and-spring-fresh quality, the visual register of English-cottage-garden-and-French-bistro-chive hand-slim-grass-onion-and-spring-fresh English-cottage-garden-and-French-bistro-chive-and-fines-herbes chive-and-slim-grass-onion surfaces under English-cottage-garden-and-French-bistro-chive-and-fines-herbes Sussex-cottage-and-Lyon-bouchon spring-onion-light. Sits at the modifier-and-flavor end of the grid, parallel to dill and chervil in usage.

Kingfisher
noun

The family Alcedinidae — particularly Alcedo atthis, the European common kingfisher whose iridescent turquoise-blue plumage gives the color its name. The color refers to a male European kingfisher's wing: a saturated, slightly cool deep blue-green with the iridescent satin finish of structurally colored feathers.
