Starched Cypress

#0b917b
Notes

Starched Cypress (#0B917B) is a deep teal 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 (170°, 86%, 31%) places it in the highly saturated band at a dark 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

Starched
adjective

Old English stercan, to stiffen — past-participle of starch. As a color modifier, starched implies a clear-and-stiff-and-formal quality, the crisp color of Edwardian-period formal-evening-shirt-and-collar starched-and-pressed dress-attire. Sits at the crisp-and-finished end of the grid, parallel to pressed and ironed in usage.

Cypress
noun

The genus Cupressus, the slender Mediterranean conifers that frame Italian villa gardens and Greek cemeteries. The color refers to the dark scaled foliage of Cupressus sempervirens: a deep, slightly blue-green with the matte finish of resin-coated scale leaves. Darker than juniper, cooler than spruce, with the architectural weight of a tree shape that says Tuscany or funerary depending on context.
