Tucked Procyon Kingfisher

#1aa6b7
Notes

Tucked Procyon Kingfisher (#1AA6B7) 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 (186°, 75%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tucked
adjective

Old English tūcian, to torment / pull — past-participle of tuck. As a color modifier, tucked implies a clear-and-fitted-and-arranged quality where the hue carries the visual register of carefully-tucked-and-neatly-fitted shirt-into-trouser dress-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.

Procyon
modifier

Greek προκύων, before-the-dog. As a color modifier, procyon implies a Canis-Minor-and-bright-foretaste-of-Sirius quality, the visual register of Canis-Minor-Procyon-and-Winter-Triangle hand-Canis-Minor-and-bright-foretaste-of-Sirius Canis-Minor-Procyon-and-Winter-Triangle-and-Bortle-1-sky procyon-and-Canis-Minor-and-bright-foretaste surfaces under Canis-Minor-Procyon-and-Winter-Triangle-and-Bortle-1-sky January-and-February-winter-zenith winter-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to rigel and altair 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.
