Calm Cypress

#105e21
Notes

Calm Cypress (#105E21) is a deep green 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 (133°, 71%, 22%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Calm
adjective

Latin calma, heat of the day — paradoxically drifted in Italian to mean stillness. Used as a color modifier since the seventeenth century for hues that read as untroubled. Calm blue, calm gray: moderate saturation combined with optical quiet. Sits at the crisp-bucket near quiet and steady.

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.

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.
