Shaker Espresso

#21041c
Notes

Shaker Espresso (#21041C) is a deep magenta 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 (310°, 78%, 7%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Shaker
adjective

English Shaker, United-Society-of-Believers-in-Christ's-Second-Appearing — adjectival usage of Shaker. As a color modifier, shaker implies a neutral-and-plain-and-stripped-down quality, the neutral color of Shaker-furniture-and-craft anti-ornamental-and-functional hand-built-and-precise-craft surface-finish. Sits at the neutral-and-stripped-down end of the grid, parallel to quakerly and plain in usage.

Espresso
noun

The concentrated coffee shot extracted under pressure — Italian café standard since the late nineteenth century, with the dark roast that distinguishes it from filter coffee. The color refers to a fresh-pulled espresso in a white cup: a deep, slightly red-shifted near-black with the slight crema of suspended oils on the surface. Warmer than coal, glossier than mascara, with the café weight of a beverage measured in twenty-five-milliliter shots.
