Tailored Cathedral

#23031e
Notes

Tailored Cathedral (#23031E) is a deep violet 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 (309°, 84%, 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

Tailored
adjective

Old French tailleor, cutter — past-participle of tailor. As a color modifier, tailored implies a neutral-and-fitted-and-precise quality, the neutral color of Savile-Row-and-Gucci-tailoring hand-cut-and-fitted-precise gentleman's-and-lady's-tailoring craft-finish. Sits at the neutral-and-traditional end of the grid, parallel to fitted and bespoke in usage.

Cathedral
noun

The interior color of an aging Gothic cathedral — limestone darkened by centuries of candle smoke, incense, and city soot. The color refers to the upper walls of Notre-Dame de Paris before the 2019 fire and restoration: a soft, slightly muted dark gray with the matte finish of weathered porous stone. Cooler than smoke, warmer than slate, with the architectural weight of a building type whose interiors are read primarily in shadow.
