Utilitarian Ceres Teal

#18b196
Notes

Utilitarian Ceres Teal (#18B196) is a true teal 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 (169°, 76%, 39%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Utilitarian
adjective

Latin ūtilitās, usefulness — adjectival suffix -ian. As a color modifier, utilitarian implies a clear-and-purpose-fit-and-stripped-down quality, the crisp color of Shaker-and-Quaker anti-ornamental functional-and-no-frills craft tradition. Sits at the crisp-and-functional end of the grid, parallel to functional and workmanlike in usage.

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.

Teal
noun

Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.

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.
