Tailored Slag

#150213
Notes

Tailored Slag (#150213) 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 (306°, 83%, 5%) 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.

Slag
noun

German Schlacke, furnace dross — the deep-glassy-black silicate residue of iron-and-copper smelting, often used as the road-bed metal-aggregate in macadamized surfaces. Slag color refers to a freshly poured blast-furnace slag-pit cooling-puddle in a Lorraine ironworks: a saturated, slightly cool deep black with the glassy finish of metallurgical-silicate residue cooling on a refractory-brick floor.
