Utilitarian Oolong

#68ece1
Notes

Utilitarian Oolong (#68ECE1) 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 (175°, 78%, 67%) 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.

Oolong
noun

The partially-oxidized Chinese tea — qīng-chá (cyan tea) — with the deep blue-green liquor distinct from green tea (lower oxidation) and black tea (higher oxidation). The color refers to fresh-brewed Tieguanyin oolong: a saturated, slightly cool deep blue-green with the optical depth of partially-fermented tea liquor.
