Tailored Scoria

#170431
Notes

Tailored Scoria (#170431) is a deep indigo 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 (265°, 85%, 10%) 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 lime. 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.

Scoria
noun

Greek skōría, clinker — the deep-cool-gray gas-rich basaltic volcanic-clinker of Mauna Loa and Etna spatter-cone eruption-deposits. Scoria color refers to a Hawaii Big Island Mauna Loa scoria-cone outer slope face in midday sun: a dark cool-gray with the matte finish of vesicular-basalt with iron-rust patina on the vesicle-rim surfaces.

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.
