Clear Turret Kingfisher

#289dac
Notes

Clear Turret Kingfisher (#289DAC) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (187°, 62%, 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

Clear
adjective

From the Latin clarus, bright, distinct — used as a color modifier since the medieval period for hues without haze or mixing. Clear blue sky, clear green water: the implication is moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clean and true.

Turret
modifier

Old French touret, small-tower. As a color modifier, turret implies a small-decorative-tower-on-castle quality, the visual register of Loire-Valley-château-and-Disney-castle-turret hand-built small-decorative-castle-and-château turret-and-spire architectural surfaces under French-and-fairy-tale-château turret-and-spire light. Sits at the modifier-and-architecture end of the grid, parallel to tower and spire 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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
