Genuine Ceres Kingfisher

#199daa
Notes

Genuine Ceres Kingfisher (#199DAA) is a true cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (185°, 74%, 38%) 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

Genuine
adjective

Latin genuinus, natural, innate — used as a color modifier since the sixteenth century for hues that read as authentic rather than imitated. Genuine indigo, genuine ochre: moderate-to-high saturation combined with the optical impression of a hue from real pigment rather than synthetic dye. Sits at the crisp-bucket alongside true and honest.

Ceres
modifier

Latin Ceres, Roman-goddess-of-grain. As a color modifier, ceres implies a dwarf-planet-and-asteroid-belt-and-grain-goddess quality, the visual register of Ceres-dwarf-planet-and-asteroid-belt hand-dwarf-planet-and-asteroid-belt-and-grain-goddess Ceres-dwarf-planet-and-asteroid-belt-and-Dawn-mission ceres-and-dwarf-planet-and-asteroid-belt surfaces under Ceres-dwarf-planet-and-asteroid-belt-and-Dawn-mission inner-asteroid-belt-and-Occator-crater dwarf-planet-light. Sits at the modifier-and-cosmic end of the grid, parallel to vesta and pallas 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.
